$CH_3CH_2NO_2$

Vedclass · Answer

(A) The reduction of nitroalkanes $(R-NO_2)$ yields primary amines $(R-NH_2)$.For example,$CH_3CH_2NO_2 + 6[H] \xrightarrow{Sn/HCl} CH_3CH_2NH_2 + 2H_2O$.Option $B$ is an alkyl nitrite,which on reduction gives alcohol and ammonia.Option $C$ is azobenzene,which on reduction gives aniline (a primary amine),but nitroalkanes are the standard textbook example for primary amine preparation via reduction.Option $D$ is an isocyanide,which on reduction gives a secondary amine $(R-NH-CH_3)$.
