The reactions of `Cl_(2)` gas with cold-dilute and hot-concentrated NaOH in water give sodium salts of two (different) oxoacids of chlorine, P and Q, respectively. The `Cl_(2)` gas reacts with `SO_(2)` gas, in presence of charcoal, to give a product R. R reacts with white phosphorus to give a compound S. On hydrolysis, S gives an oxoacid of phosphorus, T.
R, S and T, respectively are

A

`SO_(2)CI_(2)`, `PCI_(5)` and `H_(3)PO_(4)`

B

`SO_(2)CI_(2)`, `PCI_(3)` and `H_(3)PO_(3)`

C

`SOCI_(2)`, `PCI_(3)` and `H_(3)PO_(2)`

D

`SOCI_(2)`, `PCI_(5)` and `H_(3)PO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
A
`SO_(2)+CI_(2)overset(Charcoal)rarr underset(R )SO_(2)CI_(2)`
`SO_(2)CI_(2)P_(4)rarr PCI_(5)+SO_(2)`
`PCI_(5)+H_(2)O rarr underset(T)H_(3)PO_(4) +HCI`
