A translucent white waxy solid (A) reacts with excess of chlorine to give a yellowish white powder (B). (B) reacts with organic compounds containing -OH group converting them into chloro derivatives. (B) on hydrolysis gives (C) and is finally converted to phosphoric acid. (A), (B) and (C) are

A

`P_(4), PCl_(3), H_(3)PO_(4)`

B

`P_(4), PCl_(5), H_(3)PO_(3)`

C

`P_(4), PCl_(5), POCl_(3)`

D

`P_(4), PCl_(3), POCl_(3)`

Text Solution

Verified by Experts

The correct Answer is:
C
`underset((A))(P_(4))+10Cl_(2)rarrunderset((B))(4PCl_(5))`
`PCl_(5)+C_(2)H_(5)OHrarrC_(2)H_(5)Cl+POCl_(3)+HCl`
`PCl_(5)+H_(2)Orarrunderset((C))(POCl_(3))+2HCl`
`POCl_(3)+3H_(2)OrarrH_(3)PO_(4)+3HCl`
