Geometry of ammonia molcule and the hybridisation of nitrogen involved in it are

A

`sp^3`- hybridization and tetrahedral geometry

B

`sp^3` -hybridization and distorted tetrahedral geometry

C

`sp^2` -hybridization and triangular geometry

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
In the ammonia molecule N atom is `sp^3`- hybridized but due to the presence of one lone pair of `e^(-)` (i.e. due to greater `L_p - b_p` repulsion) it has distorted tetrahedral (or pyramidal) geometry.
