NCERT Class 12 Chemistry all Chapter Name

One of the core subjects for board exams is chemistry. The NCERT syllabus for class 12 chemistry covers a wide range of topics and questions, all of which have been covered by the respective sections of this article.

Students can find information on organic chemistry, acids and bases and other topics in any of the NCERT 12 chemistry textbooks. A vast majority of the questions come from these chapters.

We have included in the PDF for Class 12 NCERT Chemistry all of the important topics and questions that we have compiled from a variety of sources and determined to be relevant. It is anticipated that students who study this will have an advantage over their classmates on both the board examinations and any other entrance exams they may take.

Chapter 1: Solid State

In the NCERT Chemistry Class 12 PDF book, one of the most important chapters is Solid State. In general, the properties and internal structures of molecules and compounds are the focus of study in the field of solid-state chemistry. Solid-state concepts allow for the categorisation of compounds into a great number of different groups.

Because of the extensive scope of their influence, key ideas from solid-state chemistry are also combined with those from solid-state physics, metallurgy, crystallography and electronics.

The topics of crystalline solids, unit cell dimension and lattice structures are some of the topics that are covered in depth and given a lot of attention in the NCERT PDF Class 12 chemistry textbook.

Chapter 2: Solutions

The chapter on solutions is another crucial part of the chemistry syllabus for class 12. The term “solution” refers to a homogenous mixture that is produced by combining two or more different solutes with one or more different solvents. The substance that has been dissolved is referred to as the solute, and the medium in which it has been dissolved is known as the solvent. Water is one of the solvents that is used in almost every industry.

The various types of solutions as well as the concentration and solubility of various solids and gases in liquids are some of the primary topics that are covered in this chapter. As a component of the NCERT Chemistry Class 12 PDF, this material is intended to be thoroughly studied.

Chapter 3: Electrochemistry

Electrochemistry, which is the joint study of electronics and chemistry, is a favourite subject area for the majority of examiners and a critical chapter in the NCERT Class 12 chemistry textbook. It determines whether an electric current has been generated as a result of a chemical reaction or whether it has been produced as a result of a chemical reaction. When electrons move back and forth between an electrode and an electrolyte, the result is the production of a current of this kind in the electric circuit.

When it comes to reviewing electrochemistry, you shouldn’t look any further than our NCERT Chemistry Class 12 PDF, which places a particular emphasis on this subject and should serve as your one-stop solution.

Chapter 4: Chemical Kinetics

The study of the rates at which various chemical reactions take place is a part of the branch of chemistry known as chemical kinetics. It provides a more in-depth explanation of how the speed at which reactions typically take place can be affected by a variety of experimental conditions, such as temperature, reaction medium or the utilisation of catalysts.

The study of immediate states of a reaction, which occur between the initial state and the final product, takes place while the reaction is taking place.

Students should be sure to put a lot of effort into practising the numerous mathematical calculations that are highlighted in the Class 12 chemistry NCERT book PDF. These calculations are related to rate calculation.

Chapter 5: Surface Chemistry

Surface chemistry and surface physics are fields of study that explore the chemical and physical transformations that take place on surfaces as a consequence of the interaction between two distinct types of matter. The interfaces between a solid and a liquid, a solid and a vacuum, and a liquid and a gas are three of the most common types of interfaces that are the subject of research. Research into surface engineering focuses on the practical applications of surface chemistry.

The adsorption of liquids and gases is a common theme in surface chemistry, and this is an important chapter in the NCERT Chemistry Class 12 PDF. Students should have a basic understanding of the concept before moving on to the next section.

Chapter 6: Isolation of Elements

Since the beginning of human history, people have been able to explore the surface and core of our planet, where they have found thousands of elements either naturally occurring or in the form of ores. Ores can contain a wide variety of elements, including gold, silver, carbon, and sulphur, all of which can be extracted from the ore using various chemical processes. These ores can also contain a multitude of other elements, some of which are more common than others.

These methods of isolating elements need to be practicable enough to be carried out in a laboratory setting. The NCERT 12 Chemistry PDF provides a wealth of information on the various processes of separation, all of which ought to be thoroughly researched.

Chapter 7: The p-Block Elements

According to the electronic configurations of the various blocks of the periodic table, scientists have given each block of the table a unique name. According to these rules, the elements that can be found in groups 13 to 18 are referred to as p-block elements, and their general configuration looks like this: ns2np1-6. For the NCERT chemistry book, all of these element groups are extremely important.

The p-Block elements are the only group in the periodic table to contain all three types of elements, which are metals, nonmetals and metalloids respectively. The NCERT Chemistry Class 12 PDF provides an extensive list of the characteristics shared by all of the elements that are located in the p-block of the periodic table.

Chapter 8: d and f-Block Elements

Elements from the d and f blocks are also found in nature and are included in the periodic table. This is similar to the p-block elements.

d-block encompasses groups 3 through 12 and begins with the fourth period of the day. They are referred to as transition elements because they bridge the gap between the elements that have a strong electropositive charge in groups 1 and 2 and the elements that have a weak electropositive charge in groups 13 to 16.

In the standard periodic table with 18 columns, the elements of the f-block typically appear as a footnote. This block is composed of metals from periods 6 and 7. In the NCERT PDF for Class 12 chemistry, each of these topics is covered in greater detail.

Chapter 9: Coordination Compounds

Coordination compounds are an essential topic covered in the NCERT Chemistry Class 12 PDF. Coordination compounds are defined as compounds that contain a metal ion in their centre, which is referred to as the coordination centre, and ions of other elements joined with the centre ion, which is referred to as ligands. The coordinated covalent bonds that exist between the metallic ion and its ligands are a topic that has been the focus of extensive research for some time.

These complexes can have an overall charge, and they also exhibit a variety of unknown and unseen properties, all of which are described in greater depth in the NCERT book for chemistry class 12, available in a PDF format.

Chapter 10: Haloalkanes and Haloarenes

When they form bonds with halogen compounds, aliphatic hydrocarbons and aromatic hydrocarbons are referred to as haloalkanes and haloarenes, respectively. These are the haloalkanes and haloarenes. Because of their high electronegativity, these halogen ions can successfully take the place of hydrogen atoms in organic molecules, thereby producing the requisite compounds.

In the chemistry PDF for the Class 12 NCERT course, it is also mentioned that halogen atoms attach themselves to the sp3 hybridised carbon in alkyl groups, whereas for aryl groups, they attach themselves to the sp2 hybridised carbon. Compounds of this kind are particularly important and are used in our daily lives in a wide variety of different ways.

Chapter 11: Alcohols, Phenols and Ethers

One of the most important parts of organic chemistry is the study of the formation of alcohols and phenols, both of which result from the substitution of hydrogen atoms in aliphatic and aromatic hydrocarbons by a -OH group. Alcohols and phenols are two chemical compounds that are extremely useful to us in our day-to-day lives and also make up a significant portion of the food that we consume.

All of their applications, as well as other reactions that involve them, are discussed in the PDF for NCERT Chemistry Class 12.

Compounds are considered to be ethers when an alkoxy (R-O) or aryloxy (Ar-O) group takes the place of the hydrogen atoms in the molecule. Fragrances often require the use of ethers as an ingredient.

Chapter 12: Aldehydes, Ketones, and Carboxylic Acids

In organic chemistry, the carbonyl group (>C=O) is widely considered to be one of the most important functional groups. They are referred to as aldehydes when the carbon and hydrogen atoms have been attached to the carbonyl group. Ketones are compounds that are formed when two carbon atoms form a covalent bond with another group. And the substance is referred to as a carboxylic acid if the group forms a bond with a -OH group.

The PDF for Class 12 of the NCERT chemistry course contains all of the equations in which compounds like these participate, as well as a listing of all of their properties.

Chapter 13: Amines

Amines are organic compounds in which alkyl or aryl groups take the place of the hydrogen atoms in the ammonia (NH3) molecule, similar to other organic compounds previously discussed. Amines are the building blocks from which proteins and amino acids, which play an important role in the complex operation of our muscles and other body parts are derived.

Amines are compounds that have one atom of nitrogen and an additional lone pair of electrons. The NH2 group is referred to as the amino group because it is a functional group. The NCERT chemistry book for class 12 devotes a significant amount of space to discussions of reactions that involve amines and amides.

Chapter 14: Biomolecules

Although biology and chemistry are two distinct academic disciplines, human bodies are a combination of the two. Our bodies are made up of thousands of different types of atoms and molecules, and we would not be able to function properly without them. Biochemistry is the study of how chemicals influence the structure of human bodies and contribute to the body’s ability to function effectively.

The study of biomolecules is one of the most interesting topics covered in NCERT chemistry class 12 part 2. Carbohydrates, proteins, lipids and hormones are the four types of biomolecules that are most important to the functioning of our bodies.

Chapter 15: Polymers

The majority of the tangible items that we use in our day-to-day lives are composed of polymers in some way. Plastic, the most important polymer, is also one of the products that are used the most frequently in modern times. The PDF for NCERT Chemistry Class 12 discusses how polymers are formed as well as the various applications that polymers have.

When we take a look inside polymer molecules, we will see repeating units that are referred to as monomers. These monomers are connected to one another by means of covalent bonds. Polymers are considered to be macromolecules because of their repeating structure, which results in a very high molecular mass. These are also covered in the PDF version of the NCERT chemistry course for class 12.

Chapter 16: Chemistry in Everyday Life

When all of the above chapters are put together, students shouldn’t just see them as formulas and reactions they have to do in labs and write down on tests. Instead, they should have a big-picture view of how each chapter contributed to making the world what it is today, including everything inside and outside of us.

This chapter provides a conclusion to the entire curriculum covered in the NCERT chemistry book for Class 12 found in PDF format. This chapter covers a variety of important topics including life-saving drugs and medicines, cleaning agents, active medicinal drugs, detergents that we use and artificial food quality enhancers.
