NCERT Solutions Class 12 Chemistry Chapter 12 Aldehydes, Ketones, and Carboxylic Acids

The term – II Syllabus for the session 2022-23 of Class 12 Chemistry includes Chapter 12 Aldehydes, Ketones, and Carboxylic Acids. Carbonyl molecules such as aldehydes, ketones, and carboxylic acids are crucial in organic Chemistry. Aldehydes, Ketones and Carboxylic Acids are carbonyl compounds of utmost importance to organic Chemistry. 

Aldehydes and ketones are obtained by the ozonolysis of alkenes, the hydration of alkynes, and the oxidation of alcohols or cyanides. Carboxylic acids are obtained by the oxidation of primary alcohols or aldehydes. 

Carboxylic acids are more acidic than alcohols or phenols due to resonance stabilisation. NCERT Solutions Class 12 Chemistry Chapter 12 can assist students in revising the entire Chapter and in achieving high grades.

The Chapter “Aldehydes, Ketones, and Carboxylic Acids” will teach you the IUPAC names and common names for ketones, aldehydes, and carboxylic acids. Other topics include

  • The structure of substances that contain carboxyl and carbonyl functional groups.
  • Aldehydes, ketones, and carboxylic acids have physical properties and chemical reactions depending on their structures.
  • The acidity of carboxylic acids and their responses are affected by several factors.

Students can also cross-check their answers with the explanations while doing textbook problems to see where they fall short.

Aldehydes and Ketones are used as solvents and reagents in the synthesis of other compounds in a variety of ways. Formaldehyde, acetaldehyde, and benzaldehyde are all significant aldehydes. Formaldehyde is a preservative for biological specimens and a raw material for bakelite production. Acetaldehyde is a precursor to acetic acid. Benzaldehyde is also used in the fragrance industry. The odours and flavours of several aldehydes and ketones are well-recognised.

Class 12 Organic Chemistry is a critical component of the Chemistry curriculum. It serves as the subject’s foundation and a base for future years. It also provides a solid foundation for all competitive Examinations, including JEE and NEET. Begin by studying all of the NCERT Chapters in order and practise all the structures. All of the equations and reactions should be practised. Their physical and chemical qualities are crucial, and they must be learned in their entirety. Make sure you create an equation book for the revisions and quick references.

  • Aldehydes and Ketones are compounds that contain carbonyl groups. The boiling point of these organic compounds depends on the intermolecular force. It rises with the increase in carbon atoms. Both these compounds are polar and also soluble in water.

 

  • Students should focus on the properties of these compounds while studying for Examinations. They should also check chemical substances and physical properties to improve their marks. NCERT Solutions Class 12 Chemistry Chapter 12 can help them understand the properties of these compounds in depth. This will aid in their comprehension of these chemicals and carboxylic compounds.

  • Students should prepare for their Boards or other competitive Examinations by consulting multiple sources. They should also consult a solution book for assistance. These will assist students in gaining a thorough understanding of the issues. They can also use these books to see how to write answers on their Boards.

 

  • Students who want to study independently should compare their answers to those in the solution book. This will assist them in identifying their flaws and, as a result, it will allow them to correct them. They should, however, be sure that these sources are trustworthy.
