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) lt AsH_(3) lt PH_(3) lt NH_(3)`

D

`PH_(3) gt NH_(3) gt AsH_(3) gt SbH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
Bond angles in hydrides of group 15 elements decreases down the group. Thus, bond angle , are in the order
`NH_(3) gt PH_(3) gt AsH_(3) gt SbH_(3)`
