Question

Sulphuryl chloride ${\mathrm{SO}}_2{\mathrm{Cl}}_2$reacts with white phosphorus ${\mathrm{P}}_4$ to give-------------------?

Answer 1

The reaction of Sulphuryl chloride ${\mathrm{SO}}_2{\mathrm{Cl}}_2$ with white phosphorus ${\mathrm{P}}_4$:

1) Sulphuryl chloride reacts with white phosphorus to give Phosphorus pentachloride and Sulfur dioxide.

2) This is the preparatory reaction for Phosphorus pentachloride.

3) The reaction is as follows,

$10{\mathrm{SO}}_2{\mathrm{Cl}}_2+{\mathrm{P}}_4\to 4{\mathrm{PCl}}_5+10{\mathrm{SO}}_2$

Hence, Sulphuryl chloride ${\mathrm{SO}}_2{\mathrm{Cl}}_2$reacts with white phosphorus ${\mathrm{P}}_4$ to give Phosphorus pentachloride and Sulfur dioxide
