Question

Explain the structure of ammonia molecule using vsepr theory

Answer 1

the ammonia molecule has a trigonal pyramidal shape as predicted by the valence shell electron pair repulsion theory (VSEPR) theory with an experimentally determined bond angle of 106.7°. the central nitrogen atom has 5 outer electrons with an additional electron from each hydrogen atom.

Answer 2

Answer:

trigonal pyramidal shape

Explanation:

The Lewis structure of ammonia is shown below as:

         ..

H   :   N  :    H

          :

         H

Number of bond pairs = 3

Number of lone pairs = 1

The formula is $AB_3L$.

According to VSEPR theory, ammonia has trigonal pyramidal shape to minimize the repulsions.
