Question:
The $ BCl_3$ is a planar molecule whereas $NCl_3$ is pyramidal because
The $ BCl_3$ is a planar molecule whereas $NCl_3$ is pyramidal because
Updated On: Jul 13, 2024
- $B - Cl$ bond is more polar than $N - Cl$ bond
- $N - Cl$ bond is more covalent than $B - Cl$ bond
- nitrogen atom is smaller than boron atom
- $BCl_3$ has no lone pair but $NCl_3$ has a lone pair of electrons
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
$BCl_3$ 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.

Group 13 Elements
Group 13 is commonly known as the Boron Family. The boron family comprises:
- Boron (B)
- Aluminum (Al)
- Gallium (Ga)
- Indium (In)
- Thallium (Tl)
Element 113 (Nihonium) gets the name of ununtrium Uut. Each one of the elements has three electrons in the external shell of their nuclear structure is one of the important and mutual properties of the group.
The general electronic configuration for the group 13 elements is ns2 np1.
