Strong reducing behaviour of `H_(3)PO_(2)` is due to

A

High oxidation state of phosphorus

B

Presence of two -OH groups and one P-H bond

C

Presence of one -OH group and two P-H bonds

D

High electron gain enthalpy of phosphorus.

Text Solution

Verified by Experts

The correct Answer is:
C

`H_(3)PO_(2)` is monobasic acid and act reducing agent due to presence of two P-H bond
`H_(3)PO_(2)+2Ag_(2)O to H_(3)PO_(4) + 4Ag`
