Question

The orbitals which have unpaired electrons can only participate in hybridization.

• A. True
• B. False

Answer 1

The correct option is B

False

Generally because orbitals which have impaired electrons participate in overlapping in covalent bond. That’s why we think that only these orbitals participate in hybridization. But that’s wrong.
Let me clear this doubt for you.
Let’s take an example.
The most common example of $N{H}_3$.


→ 3 sp³ hybrid orbital will overlap with 1s orbital of three hydrogen’s.

→ 1 sp³ hybrid orbital will contain a lone pair.

From this example, you can see that orbitals which have fully paired electrons also participate in hybridization.
It contains the lone pair.
