NEET Chemistry Preparation MCQ Question
Which of the following statements about the preparation of amines is correct?
Reduction of amides yields primary amines when treated with lithium aluminium hydride.
Ammonolysis always yields only primary amines regardless of ammonia excess.
Nitriles can be reduced to tertiary amines using catalytic hydrogenation.
Primary amines can be prepared exclusively from quaternary ammonium salts.
Correct Answer
Detailed Explanation
According to the NCERT context, amides can be reduced with lithium aluminium hydride to yield amines, which supports option A. Ammonolysis does not yield only primary amines (option B), nitriles do not produce tertiary amines via catalytic hydrogenation (option C), and quaternary ammonium salts do not exclusively yield primary amines (option D).
