Question

Acid A is prepared from white phosphorus on reaction with alkali, while acid B is prepared from red phosphorus on reaction with alkali. If the total number of P – OH linkage in both molecules (one molecule each) is X and number of P – H bonds is Y, then the value of (X + Y) is

Answer 1

White $P_4+\text{alkali}\to H_{3}p{O}_2$

Red $P_4+\text{alkali}\to H_4{P}_2{O}_6$
