Question

Which of the following statement(s) is correct about $P_4{O}_6$ and $P_4{O}_{10}$?

• A. Both oxides have closed cage like structure
• B. Each oxide contains six equivalent P-O-P bonds
• C. Both $P_4{O}_6$ and $P_4{O}_{10}$ molecules have p$\pi$-d$\pi$ bonds.
• D. P-O-P bond length of $P_4{O}_6$ is greater than $P_4{O}_{10}$

Answer 1

Answer: (A), (B), (D)

The correct options are
A Both oxides have closed cage like structure
B Each oxide contains six equivalent P-O-P bonds
D P-O-P bond length of $P_4{O}_6$ is greater than $P_4{O}_{10}$

P-O-P bond length of $P_4{O}_6$ is greater than $P_4{O}_{10}$.
$P_4{O}_6$ due to the absence of $\pi$ bond, p$\pi$-d$\pi$ bond is not present.
