Question
Strong reducing behaviour of \[\ce{H3PO2}\] is due to ______.
Options
Low oxidation state of phosphorus
Presence of two –OH groups and one P–H bond
Presence of one –OH group and two P–H bonds
High electron gain enthalpy of phosphorus
Solution
Strong reducing behaviour of \[\ce{H3PO2}\] is due to presence of one –OH group and two P–H bonds.
Explanation:
\[\ce{H3PO2}\] has one O – H group and two P – H bonds.
The existence of a P – H link gives phosphorus oxyacids their reducing characteristics. It has a strong proclivity for releasing protons. As a result, it demonstrates a decreasing nature.
