NEET CHEMISTRYAldehydes, Ketones and Carboxylic AcidsEasy

Question

The product formed by the reaction of an aldehyde with a primary amine is:

A

Ketone

B

Carboxylic acid

C

Aromatic acid

D

Schiff base

Step-by-Step Solution

Aldehydes and ketones react with primary amines (R−NH2R-NH_2) in weakly acidic medium to form Schiff bases (also known as substituted imines). This is a nucleophilic addition-elimination reaction where the carbonyl oxygen is replaced by the =N−R=N-R group, eliminating a water molecule.

Reaction: R−CHO+R′−NH2→H+R−CH=N−R′(Schiff\Base)+H2OR-CHO + R'-NH_2 \xrightarrow{H^+} R-CH=N-R' (Schiff\Base) + H_2O

Exam Context & Concepts Covered

This question aligns with the NEET CHEMISTRY syllabus, specifically targeting concepts from Aldehydes, Ketones and Carboxylic Acids. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
