A
Methyl isocyanide
a $C H_{3}-N \equiv C+4[H] \stackrel{L i A H_{4}}{\longrightarrow} C H_{3} N H C H_{3}$
Dimethylamine On catalytic reduction or with lithlium aluminium hydride $(LiAlH_{4} )$ or with nascent hydrogen, alky isocyanide yield $2 ^ { \circ }$ amine whereas cyanide gives $1^{\circ}$ amine on reduction.

$(i)$ chlorobenzene is mono-nitrated to $M$
$(ii)$ nitrobenezene is mono-chlorinated to $N$
$(iii)$ anisole is mono-nitrated to $P$
$(iv)\, 2-$ nitrochlorobenzene is mono-nitrated to $Q.$
Out of $M, N, P$ and $Q$ the compound that undergoes reaction with $aq. NaOH$ fastest is
A compound having molecular formula $C_3H_6O$ , on reaction with $\begin{array}{*{20}{c}}
{\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,O} \\
{\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,||} \\
{N{H_2} - NH - C - N{H_2}}
\end{array}$ produces mainly $P$ (shows stereoisomerism) which on reaction with $KOH /$ ethylene glycol, $\Delta$ produces propane then $(P)$ is
