Solution

An atom or a group of atoms joined together in a specific manner that is responsible for the difference in chemical properties of the organic compounds is called a functional group.

Chemical properties of an organic compound are controlled by a functional group.

Examples: -OH (Alcohol), -CHO (Aldehyde), -COOH (Carboxylic Acid)
