• D. 1. (A) $\to$ q,s (B) $\to$ p,s (C) $\to$ p,r (D) $\to$ r,s

Answer 1

The correct option is A 1. (A) $\to$ p,s (B) $\to$ p,s (C) $\to$ q,r (D) $\to$ r,s

(A) Hypo phosphoric acid ($H_4{P}_2{O}_6$) has $s{p}^3$ hybridization. In this molecule all hydrogens are ionizable in water.

(B) Pyro phosphoric acid $\left(H_4{P}_2{O}_7\right)$ has $s{p}^3$ hybridization. In this molecule all hydrogens are ionizable in water.

(C) Boric acid ($H_{3}B{O}_3$) is a Lewis acid and monobasic in water.

(D) Hypo phosphorus acid $\left(H_{3}P{O}_2\right)$ has $s{p}^3$ hybridisation and is monobasic in water.

So answer is A.
