How many toluidines on reaction with ${\mathrm{NaNO}}_2/\mathrm{HCl}$ followed by ${\mathrm{H}}_3{\mathrm{PO}}_2$ treatment gives toluene.

 Product $\mathrm{Z}$

Find the molecular weight of $\mathrm{Z}.$

Molecular weight of $\mathrm{T}$ will be:

$\mathrm{Ph}-{\mathrm{NO}}_2\stackrel{\mathrm{Sn}/\mathrm{HCl}}{\to }\underset{\mathrm{HCl}, 0°\mathrm{C}-5°\mathrm{C}}{\overset{{\mathrm{NaNO}}_2}{\to }}\underset{\mathrm{Ph}-\mathrm{OH}}{\overset{\mathrm{Basic} \mathrm{medium}}{\to }}$ Product $\mathrm{Y}$

Find the molecular weight of $\mathrm{Y}$ report your answer as $\frac{\mathrm{Molecular} \mathrm{weight}}{2}.$
