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

Options

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

Answer

B

Explanation

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.
