Question

The change in bond angle as the s-character of hybridized orbital decreases is,

• A. Decreases
• B. Increases
• C. Does not change
• D. Becomes zero

Answer 1

Answer: (A)

As the s-character of hybridized orbitals decreases the bond angle also decreases

In $s{p}^3$ hybridisation: $s-$ character $1/4$ , bond angle $109^o$

In $s{p}^2$ hybridisation: $s-$ character $1/3$ , bond angle $120^o$

In $sp$ hybridisation: $s-$ character $1/2$ , bond angle $180^o$
