These revision notes on Aldehydes, Ketones, and Carboxylic Acids help students with a quick revision. To score good grades in this chapter, you need to remember the common and IUPAC names of aldehydes, ketones, and carboxylic acids. Also, revising the structures of the compounds containing functional groups such as carbonyl and carboxyl groups is necessary.
Different methods of preparing Aldehydes:
- From acyl chloride
- From nitriles and esters
- From hydrocarbons
Different methods of preparing Ketones:
- From acyl chlorides
- From nitriles
- From substituted benzenes or benzene
Aldehydes and ketones undergo similar reactions as they both have same carbonyl functional group:
- Nucleophilic addition reactions
- Reactions due to a-hydrogen
- Other reactions such as Cannizzaro reaction and Electrophilic substitution reaction

Frequently asked Questions on CBSE Class 12 Chemistry Notes Chapter 12: Aldehydes, Ketones and Carboxylic Acids
What are the uses of ‘Aldehydes’?
Aldehydes are used in tanning, preserving, and embalming and as a germicide, fungicide, and insecticide for plants, vegetables and production of certain polymeric materials.
What is ‘Nucleophilic addition’?
A nucleophilic addition reaction is a chemical addition reaction in which a nucleophile forms a sigma bond with an electron deficient species.
What is the valency of hydrogen?
Hydrogen has only one valence electron and can form only one bond with an atom that has an incomplete outer shell. Hence the valency of hydrogen is one.
