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 atoms

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
(Central Borm atom) No lone pair of electron is available in `BCl_(3)`.

One lone pair of electron is available on N-atoms , it occupies a corner in the tetrahedral arrangement . Therefore , `NCl_(3)` appears pyramidal in shape.
