MCQ
The bond angle in $P{H_3}$ is
- ✓Much less than $N{H_3}$
- BEqual to that of $N{H_3}$
- CMuch greater than $N{H_3}$
- DSlightly greater than $N{H_3}$
✓
Answer
Correct option: A.
Much less than $N{H_3}$
(a) In fifth group hydride bond angle decreases from top to bottom $N{H_3} > P{H_3} > As{H_3} > $ $Sb{H_3} > Bi{H_3}$.
