MHT CET 2025 Chemistry question

Identify the product obtained when nitro ethane is treated with Sn-HCl under ideal condition

(A)EthanamineCorrect
(B)Acetamide
(C)Formamide
(D)Methanamine

Answer: (A)

Solution

Nitroalkanes are reduced to primary amines by metals in acid (Sn/HCl, Fe/HCl) or by catalytic hydrogenation: CH_3CH_2NO_2+6[H]\xrightarrow{Sn/HCl}CH_3CH_2NH_2+2H_2O. The carbon skeleton is unchanged, so nitroethane gives ethanamine
