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_3gtPH_3gtSbH_3`

C

`SbH_3gtAsH_(3)gtPH_3gtNH_3`

D

`PH_(3)gtNH_(3)gtAsH_(3)gtSbH_3`

Text Solution

Verified by Experts

The correct Answer is:
A
As the electronegativity of the central atom decreases and the size increases, the bond angle decrease in similar molecules.
