What is the shape of an ammonia molecule?

A. bent

B. tetrahedral

c. trigonal pyramidal

D. linear

E. trigonal bipyramidal

Answer: The shape of an ammonia molecule is trigonal pyramidal.

Explanation: Ammonia has a tetrahedral arrangement of 3 hydrogen atoms and a lone pair around the central nitrogen atom. However, due to the fact that classification of molecular shape considers only the bonded atoms and not the lone pair, the shape is referred to as trigonal pyramidal.

C.

Explanation:

Trigonal pyramidal. It is not trigonal planar (tetrahedal) because of the lone pair of electron in the nitrogen atom.
