Vedclass · Answer

(D) The given reaction is the $Hoffmann$ $Bromamide$ degradation reaction. In this reaction,an amide is treated with $Br_2$ and $KOH$ to form a primary amine with one carbon atom less than the original amide. The reaction proceeds with the retention of configuration at the chiral center where the $NH_2$ group is attached. Therefore,the $CONH_2$ group is replaced by an $NH_2$ group while maintaining its stereochemical orientation (wedge). The $Et$ group remains on the dash as it was in the reactant.
