Write structures and IUPAC names of
(i) the amide which gives propanamine by Hoffmann bromamide reaction.
(ii) the amine produced by the Hoffmann degradation of benzamide.

Text Solution

Verified by Experts

Propanamine contains three carbons. Hence, the amide molecules must contains four carbon atoms.
Structures of the amide with four carbon atoms are given below:
`CH_(3)-CH_(2)-CH_(2)-underset(O)underset(||)C-NH_(2)`
