Among the following, the number of compounds that can react with `PCl_(5)` to give `POCl_(3)` is `O_(2)`,`CO_(2)`,`SO_(2)`,`H_(2)O`,`H_(2)SO_(4)`,`P_(4)O_(10)`.

Options

A. 1
B. 2
C. 3
D. 4

Answer

D

Explanation

`PCl_(5)` produces `POCl_(3)` with the following reagents .
`2PCl_(4)+2SO_(4) to 2POCl_(3)+SOCl_(2)`
`PCl_(5) +H_(2)O to POCl_3 +2HCl `
`2PCl_(5)+H_(2)SO_(4) to SO_(2)Cl_(2) +2POCl_(3) +2HCl `
`6PCl_(5)+P_(4)O_(10) to 10POCl_(3)`
