Question

Promotion of electron is not essential condition prior to hybridization.

• A. True
• B. False

Answer 1

The correct option is A

True

If you are thinking that promotion of electron is very necessary for hybridization, then you are wrong.

→ This is one of the main characteristics of hybridization.
For proper explanation, let’s take an example.
Let’s take a look at NH₃.

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

→ 1 sp³ hybrid orbital will contain a lone pair.

Therefore,
Promotion of electrons is not a necessary condition for hybridization.
