Strong reducing behaviour of H(3)PO(2) i...

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

A

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

B

high electron gain enthalpy of phosphorus

C

high oxidation state of phosphorus

D

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

Text Solution

Verified by Experts

The correct Answer is:
A

The oxy acid of phosphours which contain `P-H` bond act as a reducing agent or reductant

In `H_(3)PO_(2)` One-OH group and two P-H bond are present.
