Important in food production and biosynthesis
Ammonia is trigonal pyramidal in shape with H-N-H bond angles of ~109.5°. The VSEPR explanation for this shape is that there are four electron groups around the nitrogen - three bonding groups and one nonbonding pair group. In terms of hybridization, the geometry is explained by sp3 hybridized orbitals, with the unshared pair occupying one of the orbitals.
