The active site or the functional part of organic compounds is called the functional group.
Functional group
Definition:
A functional group is an atom or group of atoms that gives characteristic chemical properties to an organic compound.


Chemical properties depend on the functional group because it takes part in a chemical reaction.
Physical properties depend on the remaining part of the molecule (alkyl group).
Importance of Functional group :
- Functional groups provide the basis for naming ( nomenclature) organic compounds.
2. Each functional group represent a different class/family of an organic compound.
(All compounds with the same functional group =same class/family)
Over six million organic compounds have been divided into homologous series on the basis of functional groups.
3. A functional group is an active site or functional part of an organic compound.
Compounds in the same class = similar chemical properties
Classification of Organic Compounds on the basis of Functional groups:
