BCl3 molecule is planar while NCl3 is py...

`BCl_3` molecule is planar while `NCl_3` is pyramidal because

A

`B-Cl` bond is more polar than `N-Cl` bond

B

`N-Cl` bond is more covalent than `B-Cl` bond

C

nitrogen atom is smaller than boron atom

D

`BCl_3` has no lone pair but `NCl_3` has a lone pair of electrons

Text Solution

Verified by Experts

The correct Answer is:
D
`BCl_3` have `sp^2` hybridisation and no lone pair of electron on central atom but `NCl_3` have `sp^3` hybridisation and also contains one lone pair of electron on nitrogen , so `BCl_3` is planar.
