Expert Answer:

i) It can be defined as the process of intermixing of the orbitals of slightly different energies so as to redistribute their energies, resulting in the formation of new set of orbitals of equivalent energies and shape.

ii) Formation of ammonia molecule:
In ammonia molecule, the nitrogen atom is sp3 hybridized.
Three sp3-hybrid orbitals of N atom are used for forming sp3-s (sigma) bonds with H atoms.
The fourth sp3-hybrid orbital carry lone pair of electrons.
The relatively larger lp-bp interactions cause H-N-H angle to decrease from 109o 28' to 107o
