Current Question (ID: 10627)

Question:

$\text{An oxyacid among the following that contains both P-H and P-P bonds simultaneously is:}$

Options:

1. $\text{H}_4\text{P}_2\text{O}_5$
2. $\text{H}_4\text{P}_2\text{O}_7$
3. $\text{H}_4\text{P}_2\text{O}_6$
4. $\text{None of the above}$ (Correct)

Solution:

$\text{The structure is as follows:}$ $\text{(1) H}_4\text{P}_2\text{O}_5 \text{ Pyrophosphorous acid}$ $\text{(2) H}_4\text{P}_2\text{O}_7 \text{ Pyrophosphoric acid}$ $\text{(3) H}_4\text{P}_2\text{O}_6 \text{ Hypophosphoric acid}$ $\text{From the structure, it is clear that none of the given compounds contains P-H and P-P bonds simultaneously}$
