Aldehydes Ketones and Carboxylic Acids Important Questions for NEET Overview

Aldehydes, ketones, and carboxylic acids are part of the organic chemistry syllabus. This chapter covers the nomenclature, preparation methods, physical and chemical properties, and distinguishing tests for these compounds. Over the last five years, this chapter has had an approximate weightage of 9% in the NEET exam, making it an important section for focused preparation.

What are Aldehydes Ketones and Carboxylic Acids?

Aldehydes are organic compounds containing the –CHO functional group. Some common examples include formaldehyde (HCHO) and acetaldehyde (CH3CHO). Ketones are organic compounds with the C=O functional group bonded to two carbon atoms. A well-known example is acetone (CH3COCH3). Carboxylic acids contain the –COOH functional group, with acetic acid (CH3COOH) being a widely recognized example.

These compounds are widely used in industries, medicine, and biological systems, making their understanding essential.
