Chapter 1. The Solid State

Class 12 Chapter 1, the solid-state, is a vital chapter that helps you understand the basics of Chemistry. It focuses on the state of matter. The state of matter forms the fundamentals for many chapters at a later stage. Solids have a definite shape, volume, and mass due to the very short distance between the fixed position of each particle and strong interactions between them. CBSE Class 12 Chemistry Notes are handy and reliable as they are prepared after analysing the previous year’s question papers to include all the crucial topics.

Chapter 2. Solutions

A solution comprises a solute and a solvent. Solution is defined as a homogeneous mixture of two or more than two substances. They are classified into solid solutions, gaseous solutions and liquid solutions. CBSE Class 12 Chemistry Notes assist students by covering every topic and subtopic regarding solutions.

Chapter 3. Electrochemistry

An electrochemical cell generates a potential difference between electrodes by chemical reactions. It comprises two-electron conductors separated by an ionic conductor and connected by an electron conductor. The two metallic electrodes are submerged in the electrolytic solution. Essential components of this cell are explained well in CBSE Class 12 Chemistry Notes.

Chapter 4. Chemical Kinetics

The most vital topic in physical Chemistry is chemical kinetics, which guides students to understand the different aspects of a chemical reaction. The term ‘kinetics’ is related to the rate of change of some quantity. The chemical reactions can be classified as fast, moderate, and slow reactions. In CBSE Class 12 Chemistry Notes, you will learn more about chemical kinetics and various reaction rate factors.

Chapter 5. Surface Chemistry

Surface Chemistry is defined as the study of the phenomenon occurring on the surface of a substance. It is the study of chemical phenomena that appear at the interface of two surfaces: solid-gas, solid-liquid, solid-vacuum, liquid-gas, etc. Some applications of surface Chemistry are known as surface engineering. In CBSE Class 12 Chemistry Notes, you can learn the day-to-day application of the same.

Chapter 6. General Principles and Processes of Isolation of Elements

The extraction and isolation of elements from their combined form involves various Chemistry principles. The entire technological and scientific process used to isolate the metal from its ore is Metallurgy. Some general principles are very common to all the extraction processes of metals, and you can study more about it in our step-by-step guide on chemical extraction in our CBSE Class 12 Chemistry Notes.

Chapter 7. The p-Block elements

The p-Block elements are found in the periodic table group 13 to 18. The p-Block elements can be found on the right-hand side of the periodic table and include elements like boron, oxygen, nitrogen, fluorine, nitrogen families ox, etc., along with noble gases, excluding Helium. Students can refer to the questions and solutions in CBSE Class 12 Chemistry Notes.

Chapter 8. The d & f block Elements

d block elements fill the middle layer of the periodic table. On the other side, f block elements are found outside at the bottom of the periodic table. They have a high boiling point and melting point. The metallic properties exhibited by the transition elements are thermal conductivity and high tensile strength.

These elements have been explained in detail with examples and diagrams in CBSE Class 12 Chemistry Notes. 

Chapter 9. Coordination Compounds

Transition metals usually form coordination compounds or complex compounds. Coordination compounds are molecules or ions coordinated or linked to a transition metal. The coordination number of any Coordination compound is the total number of ligands associated with the transition metal ion. 

The best platform for CBSE Class 12 Chemistry Notes is the Extramarks website, which provides the latest revision notes for a smooth overall preparation.

Chapter 10. Haloalkanes and Haloarenes

Alkyl/ Aryl halides are classified as mono, di, and polyhalogen depending upon the number of halogen atoms in a compound. Halogen atoms are more electronegative when compared to carbon. These chemicals are extensively used, and their application is seen in flame retardants, refrigerants, propellants, pharmaceuticals, etc. All the requisite details of this subject are detailed in CBSE Class 12 Chemistry Notes.

Chapter 11. Alcohols, Phenols, and Ethers

The main topics covered in chapter 11 Alcohol, Phenols and Ethers are their structure, nomenclature, classification, preparation, physical and chemical properties with salient examples. The most fundamental topics of Organic Chemistry, which have wide applications in the industries, are covered in this chapter. All the essential topics and concepts useful for the exam are covered in CBSE Class 12 Chemistry Notes.

Chapter 12. Aldehydes, Ketones, and Carboxylic Acids

Aldehydes, ketones, and carboxylic Acids are some vital organic compounds containing carbonyl groups. These molecules are highly polar and hence have high boiling temperatures. To make these concepts clear, subject experts have written NCERT Books which are accurate and reliable. Chemistry subjects revolve around various concepts and reactions. Students must go through the full CBSE Class 12 Chemistry Notes to understand them better.

Chapter 13. Amines

Amines are derived from ammonia acquired by replacing hydrogen atoms in alkyl groups. Simple amines are formed when aryl or alkyl groups of tertiary and secondary amines are the same. They are formed from halides, amides, nitro compounds, or imides. The expert faculty at Extramarks have prepared CBSE Class 12 Chemistry Notes by keeping the constantly changing CBSE curriculum in mind.

Chapter 14. Biomolecules

The organic compounds which form the basis of life are called Biomolecules. They are responsible for the growth and maintenance of the living system. The link that relates biomolecules to living organisms is Bio-molecules → Organelles → Cells → Tissues → Organs → Living organisms. An excellent CBSE Class 12 Chemistry Notes revision material is available on Extramark, which covers elaborate details on this chapter.

Chapter 15. Polymers

Polymers are derived from monomers. They consist of repeating structural units of high molecular mass, Macromolecules. They may occur in a synthetic or natural form and are classified based on origin, structure, etc. To make this chapter easier to study and prepare, you can refer to Extramarks CBSE Class 12 Chemistry Notes, which provide a strong base in the subject.

Chapter 16. Chemistry in Everyday Life

The study of materials and development of new materials for the betterment of humanity, is called Chemistry. In everyday life, medicine is used as a chemical agent which affects human metabolism to cure the illness. Chemistry has always been a part of human life. CBSE Class 12 Chemistry Notes give students a detailed knowledge of Chemistry and its variables.
