Question

How many N atoms are $s{p}^2$ hybridised in the given cation?

• A. 3
• B. 4
• C. 5
• D. 6

Answer 1

The correct option is C 5

Hybridisation of nitrogen atoms in the given cation

The nitrogen atoms whose steric number is three, will be $s{p}^2$ hybridised.
Steric number = number of $\sigma$-bonds + number of lone pairs.

There are five $s{p}^2$ hybridised nitrogen atoms in the given cation.
So, option (C) is the correct answer.
