The correct sequence of decrease in the bond angles of the following hydrides is

A

`NH_3` gt `PH_3`gt `AsH_3`gt `SbH_3`

B

`NH_3`gt `AsH_3` gt `PH_3`gt `SbH_3`

C

`SbH_3`gt `AsH_3` gt `PH_3`gt `NH_3`

D

`PH_3`gt `NH_3` gt `AsH_3`gt `SbH_3`

Text Solution

Verified by Experts

The correct Answer is:
A
In similar molecules, as the electronegativity of the central atom decreases and the size increases, the bond angle decreases
