Question

Which option is it...

Answer 1

NH3 or Ammonia is the answer
It has a lone pair and three ligands which contribute to its high dipole moment making it polar in nature
By applying steric number rule
Hybridisation for NH3 will be
(5+3)/2
=4
which implies sp3 hybridisation
The geometry of this molecule is Tetrahadal
but shape is Trigonal Bipyramidal
