A
${\mathrm{POCl}}_{3},{S}_{2}{\mathrm{Cl}}_{2}$ and $2$
B
${\mathrm{PCl}}_{3},{S}_{2}{\mathrm{Cl}}_{2}$ and $4$
C
${\mathrm{PCl}}_{3},{S}_{2}{\mathrm{Cl}}_{2}$ and $2$
D
${\mathrm{POCl}}_{3},{S}_{2}{\mathrm{Cl}}_{2}$ and $4$

Solution

Thionyl chloride reacts with white phosphorus to produce phosphorus trichloride. The other side products in this reaction are sulphur dioxide and Sulphur monochloride.

${P}_{4}+8{\mathrm{SOCl}}_{2}\rightarrow 4{\mathrm{PCl}}_{3}+4{\mathrm{SO}}_{2}+2{S}_{2}{\mathrm{Cl}}_{2}$

Hence $A={\mathrm{PCl}}_{3},x=4,B={S}_{2}{\mathrm{Cl}}_{2}$
