Question

Identify A, B and C.

\[\ce{CH3 - NO2 ->[LiAlH4] A ->[2CH3CH2Br] B ->[H2SO4] C}\]

Answer 1

\[\begin{array}{cc}
\ce{\underset{(Nitro methane)}{CH3NO2} ->[LiAlH4][6(H)/-2H2O] \underset{\underset{(A)}{(Methylamine)}}{CH3NH2} ->[2CH3CH2Br][-2HBr] \underset{\underset{(B)}{(N, N-diethyl methylamine)}}{(CH3CH2)2NCH3} ->[H2SO4] [(CH3CH2)2NH^+] HSO^-_4}\\

\phantom{.............................................................................}\ce{\underset{\underset{(C)}{(Quarternary salt)}}{CH3}}
\end{array}\]
