When a nitrogen atom covalently bonds to three hydrogen atoms to form ammonia, it still retains one pair of unshared electrons.
According to VSEPR theory, what is the shape of an ammonia molecule?
OA. linear triatomic
OB. tetrahedral
OC
pyramidal
OD. trigonal planar

Answer:

C. Trigonal pyramidal

Explanation:

According to the valence shell electron pair repulsion theory, the shape of ammonia is trigonal pyramidal in nature.

The bond angle is 107° and it has bond pair of 3 and lone pair of 1.

  • The variations in the bond angles of molecules can be explained by the VSEPR model.
  • This model determines the total number of electron pairs surrounding the central atom of a specie.

A tetrahedral is exhibited by methane

Trigonal planar is exhibited by BF₃
