Vedclass · Answer

(B) The reaction of white phosphorus $(P_4)$ with sodium hydroxide $(NaOH)$ solution is a disproportionation reaction. The chemical equation is: $P_4 + 3NaOH + 3H_2O \rightarrow PH_3 + 3NaH_2PO_2$. Here,$PH_3$ is phosphine and $NaH_2PO_2$ is sodium hypophosphite. Sodium hypophosphite $(NaH_2PO_2)$ is the salt of hypophosphorous acid $(H_3PO_2)$. Since $H_3PO_2$ has only one ionizable hydrogen atom,it is a monobasic acid. Therefore,the products are phosphine and the sodium salt of a monobasic acid.
