Interpretation Introduction

a)

Interpretation:

The product of the reaction given is to be predicted and a mechanism for the reaction is to be provided.

Concept introduction:

In Hofmann degradation reaction amides give amines with one carbon less than that in amides. Amides react in the presence of a base to give an isocyanate which upon hydrolysis yields the amine liberating CO₂.
