Question

Column I contains method of preparation of Oxoacids of phosphorus or its salt. Column II contains types of bonds in the compound formed in products.

$\begin{array}{ccccc}& \text{Column-1}& & \text{Column-2}& \\ \left(A\right)& \text{Red}{P}_4+\text{Alkali}& \left(P\right)& \text{P-H bond}& \\ \left(B\right)& \text{While}{P}_4+\text{Alkali}& \left(Q\right)& \text{P-O-P bond}& \\ \left(C\right)& H_{3}P{O}_4\underrightarrow{\Delta }& \left(R\right)& \text{P-OH bond}& \\ \left(D\right)& 3H_{3}P{O}_3\underrightarrow{B{r}_2}& \left(S\right)& \text{P-P bond}& \\ & & \left(T\right)& \text{P=O bond}& \end{array}$

• A. a
• B. b
• C. d
• D. c

Answer 1

The correct option is B b

A(R,S,T); B(P,R,T); C(Q,R,T); D(Q,R,T)

$A.\text{Red}{P}_4+\text{Alkali}\to H_4{P}_2{O}_6$


$B.\text{White}{P}_4\text{Alkali}\to H_{3}P{O}_2$


$C.H_{3}p{O}_4\underrightarrow{\Delta }{H}_4{P}_2{O}_7$



$D.3H_{3}P{O}_3\underrightarrow{B{r}_2}(HP{O}_3{)}_3$
$\Delta$
