As the p - charcter increases the bond angle in in hydrid orbital formed by a and atomic orbitals

A

Decreases

B

Increases

C

Doubles

D

Remains unchanged

Text Solution

Verified by Experts

The correct Answer is:
A
As p-character increases the bond angle decreases.
In sp - p-character `1/2`, bond angle `-180^@`
In `sp^2 - p` - character `2/3`, bond angle `- 120^@`
In `sp^3` - p - character `3/4`, bond angle `-109^@`
