In compounds of type `ECI_(3)`, where `E=BP`, As or `B`, the angles `CI-E-CI` for different `E` are in the order

A

`B gt P= As =Bi`

B

`B gt P gt As gt Bi`

C

`B lt P=As =Bi`

D

`B lt P lt As lt Bi`

Text Solution

Verified by Experts

The correct Answer is:
B
`B gt P gt As gt Bi`
As we go down the group bond angle decreases because repulsion between bonded pairs of electron decreases
