Hybridisation

Overlapping

It is defined as the process by which atomic orbitals of slightly different energies combine to form a new set of equivalent orbitals known as hybrid orbitals.

It is defined as the process by which different types of bond are formed between the orbitals of two or more atoms.

This term is used in reference to one atom.

Orbital overlapping is used in reference to two or more atoms.

There is no bond formation and involves just redistribution of energy.

There is bond formation.

Hybrid orbitals are named by considering the type and number of atomic orbitals from which they arose.

Single, double and triple bond are decided from the overlap of s and p orbitals.

Hybridisation provides exact explanation for the structure of compounds like Methane (CH₄).

Concept of maximum orbital overlap fails to explain structure of compounds like Methane (CH₄).
