The correct sequence of decrease in the ...

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.
