Which one of the following molecules has the smallest bond angle ?

A

`NH_3`

B

`PH_3`

C

`H_2O`

D

`H_2Se`

Text Solution

Verified by Experts

The correct Answer is:
D
All these molecules involved `sp^3`-hybridisation with one lone pair (`NH_3 and PH_3`) or two lone pairs (`H_2O`, `H_2Se` and `H_2S`). More the number of lone pairs, smaller is the angle. Out of `H_2O`, `H_2S` and `H_2Se`, H-Se-H angle in `H_2Se` is least (`91^(@)`).
