Chemical Bonding And Molecular Structure Question 252

Question: Geometry of ammonia molecule and the hybridization of nitrogen involved in it are [MH CET 2004]

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

Show Answer

Answer:

Correct Answer: B

Solution:

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.
