(image) $\xrightarrow[(273-278\,K)]{NaN{{O}_{2}}/HCl}X$  ${\mkern 1mu} \xrightarrow{{N,N\, - \,\dim ethyl\,\,aniline}}Y$

$'Y'$ નું બંધારણ શું હશે ?

$(1)$   $C{H_3}C{H_2}N{H_2}$                    $(2)$   $\begin{array}{*{20}{c}}
{\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,C{H_2}C{H_3}}\\
{\,\,\,\,\,\,\,\,\,\,\,\,\,\,|\,\,\,\,}\\
{\,C{H_3}C{H_2}NH\,\,\,\,\,\,\,}
\end{array}$

$(3)$   $\begin{array}{*{20}{c}}
{\,\,\,\,\,\,\,C{H_3}}\\
{\,|}\\
{{H_3}C - N - C{H_3}}
\end{array}$                                $(4)$     $\begin{array}{*{20}{c}}
{\,\,\,\,\,\,\,C{H_3}}\\
{\,|}\\
{Ph - N - H}
\end{array}$

ઉપરોક્ત પ્રક્રિયાને ધ્યાનમાં લેતા, અનુક્રમે $X$ અને $Y$ છે
