Question

Identify compounds A, B and C in the following sequence of reaction.

\[\ce{CH3NH2 ->[CH3Br] A ->[CH3COCl] B ->[B2H6] C}\]

Answer 1

\[\begin{array}{cc}
\ce{\underset{(Methyl amine)}{CH3NH2} ->[CH3Br] \underset{\underset{(A)}{(N, N-dimethyl amine)}}{(CH3)2NH} ->[CH3COCl] \underset{\underset{(B)}{(N, N-dimethyl acetamide)}}{(CH3)2N - COCH3} ->[B2H6] (CH3)2N -CH - CH3}\\
\phantom{.........................................................................}|\\
\phantom{...........................................................................}\ce{\underset{\underset{(C)}{(N, N-dimethyl amine)}}{OH}}
\end{array}\]
