Question

Which path gives propan-1-amine as the product in the reaction below?

(a) Only A

(b) Only B

(c) Both A and B

(d) Not A nor B

This question was posed to me in quiz.

This interesting question is from Preparation of Amines topic in section Amines of Chemistry – Class 12

Answer 1

The correct option is (a) Only A

The explanation is: Propanamine has three carbon atoms and so does the parent amide. So, the reduction of CO to CH2 will give the required compound. Whereas in path B, the amide undergoes Hoffmann bromamide degradation to give ethanamine.
