What is the difference between the hybridization of carbon atoms’ valence orbitals in saturated and unsaturated hydrocarbons?

Type of hybridisation

Explanation:

For example, saturated hydrocarbons have sp3 hybridisation while unsaturated hydrocarbons have either sp2 or sp hybridisation.

Example: Ethane (C2H6) has sp3 hybridisation and ethene (C2H4) has sp2 hybridisation and Ethyne (C2H2) has sp hybridization.
