The strong reducing behavior of hypophosphorous acid () is primarily due to: — p Block Elements Chemistry Question

💡 Solution & Explanation

Hypophosphorous acid ($H_3PO_2$) has a tetrahedral structure around phosphorus containing one $P=O$ bond, one $P-OH$ bond, and two $P-H$ bonds. The presence of these two $P-H$ bonds is directly responsible for its strong reducing properties.
