Vedclass · Answer

(B) The reaction of white phosphorus $(P_{4})$ with alkali $(NaOH)$ is given by: $P_{4} + 3 NaOH + 3 H_{2}O \rightarrow PH_{3} + 3 NaH_{2}PO_{2}$ The product $NaH_{2}PO_{2}$ is the salt of hypophosphorous acid,also known as phosphinic acid $(H_{3}PO_{2})$. In the structure of phosphinic acid $(H_{3}PO_{2})$,there are two $P-H$ bonds,one $P=O$ bond,and one $P-OH$ bond. Therefore,the correct answer is phosphinic acid.

The oxoacid of phosphorus that is easily obtained from a reaction of alkali and white phosphorus and has two $P-H$ bonds,is
