The major products P and Q formed in the following reactions of benzonitrile are

Options

A.
B.
C.
D.

Answer

C

Explanation

When ` C_(6) H_(5) CN` reacts with Na//EtOH, ` C_(6)H_(5)CN`
undergo for reduction and `- C -= N ` , changes to ` - CH_(2) - NH_(2)`
Thus, the product (P) is

The reaction occurs as follows :

When ` C_(6) H_(5) CN` reacts with (i) HCl (cone. cold) and (ii) ` Br_(2)//KOH` , it gives corresponding primary amine with one C-atom less, as in parent formula (using Hoffmann - Bromamide degradation reaction).
Thus, the final product is
` (##ARH_5Y_SP_06_05_19_01_E03_040_S03.png" width="80%">
The whole reaction is as follows :
` (##ARH_5Y_SP_06_05_19_01_E03_040_S04.png" width="80%">
Hence, option (c) is the correct answer .
