Current Question (ID: 10570)

Question:

$\text{The strong reducing behaviour of H}_3\text{PO}_2 \text{ is due to:}$

Options:

1. $\text{Presence of one -OH group and two P-H bonds.}$ (Correct)
2. $\text{High electron gain enthalpy of phosphorus.}$
3. $\text{High oxidation state of phosphorus.}$
4. $\text{Presence of two -OH groups and one P-H bond.}$

Solution:

$\text{Hint: The compound which has P-H bonds act as strong reducing agents.}$ $\text{Explanation:}$ $\text{All oxyacids of phosphorus that have P-H bonds act as strong reducing agents. H}_3\text{PO}_2 \text{ has two P-H bonds hence, it acts as a strong reducing agent.}$ $\text{The structure is as follows:}$ $\text{[Structure shows phosphorus atom with double-bonded oxygen, one -OH group, and two P-H bonds]}$
