Question

As the s-character of hybridised orbital increases, the bond angle

Options

• increase

• decrease

• becomes zero

• does not change

Answer 1

increase

Explanation:

The bond angle increases as the s-character of the hybridised orbital increases. The hybridised orbitals, percent s-chatracter, and bond angles are shown in the table below.

Hybridised orbitals	% s-character	Bond angle
sp3	25	109.5°
sp2	33	120°
sp	50	180°
