White phosphorus reacts with sulphuryl chloride to form `PCl_(5)` and X. Chlorine reacts with X in the presence of wood charcoal to form Y. X and Y are respectively

Options

A. `SO_(2), SO_(2)Cl_(2)`
B. `SO_(2), SCl_(4)`
C. `SO_(3), SO_(2)Cl_(2)`
D. `SO_(3), SCl_(4)`

Answer

A

Explanation

White phosphorus reacts with sulphuryl chloride to form `PCl_(5)` and `SO_(2)(X)`. Chlorine reacts with `SO_(2)` in presence of wood charcoal to form `SO_(2)Cl_(2)(Y)`. The reaction ca be written as : `P_(4)("white") + 10 SO_(2)Cl_(2) rarr 4 PCl_(5) + underset((X))(10 SO_(2))`
`underset((X))(SO_(2)) + Cl_(2) overset("Wood charcoal")rarr underset((Y))(SO_(2)Cl_(2))`
