Q. In $P_{4}O_{10}$ the
A) Second bond in $P = O$ is formed by $p\pi - d\pi$ back bonding
B) $P = O$ bond is formed by $p\pi - p\pi$ bonding
C) $P = O$ bond is formed by $d\pi - d\pi$ bonding
D) $P = O$ bond is formed by $d\pi - d\pi\ - 3\sigma$ back bonding
Explanation
(a)
In the structure of $P_{4}O_{10}$, each phosphorus atom is covalently linked with three oxygen atoms and each oxygen atom is bonded to two phosphorus atoms. Each phosphorus atom is also linked with an additional oxygen atom with the help of a coordinate linkage by lone pair of electron present on P atom.
