Question

Predict the major product $ P $ in the following sequence of reactions:
(i) HBr, benzoyl peroxide 
(ii) KCN 
(iii) Na(Hg), $C_{2}H_{5}OH$

• A. $C_6H_5-CH_2-CH_3$
• B. $C_6H_5-CH_2-NH_2$
• C. $C_6H_5-CH_2-CN$
• D. $C_6H_5-NH_2$

Hint:

In the presence of KCN, alkyl halides undergo nucleophilic substitution to form nitriles, which is a common reaction. The subsequent step does not affect the nitrile in this case.
