Question

Identify the incorrect statement from the following:

Options

A.Nitrogen can form $p\pi - p\pi$ multiple bonds with itself.
B.$P\left( C_{2}H_{5} \right)_{3}$ and $As\left( C_{6}H_{5} \right)_{3}$ form $d\pi - d\pi$ bond with tr
C.Phosphorus, arsenic and antimony show catenation property.
D.Nitrogen can form $d\pi - p\pi$ bond with oxygen.

Solution

Sol. [Key Concept: Evaluating statements — pick the incorrect one]

- Both nitrogen and oxygen do not contain d-orbitals so it cannot form $d\pi - p\pi$ bond.

- Phosphorus and Arsenic can form $d\pi - d\pi$ bond with trAns.ition metals. Since both have vacant d-orbitals by which it can interact with trAns.ition metals and can involve in $d\pi - d\pi$ interaction.

- Phosphorous, Arsenic and Antimony show catenation property.
