What are functional groups in NCERT?

In NCERT Chemistry (especially Class 10 and 11), a functional group is defined as:

Key Points about Functional Groups

• Functional groups are the reactive part of a molecule responsible for chemical reactions.
• They are usually attached to a hydrocarbon chain (the parent chain).
• Compounds with the same functional group exhibit similar chemical behavior.

Common Functional Groups in NCERT

Importance of Functional Groups

• Helps classify organic compounds into homologous series.
• Allows prediction of chemical reactions.
• Basis of IUPAC nomenclature.
• Essential for understanding organic chemistry.

Final Definition

A functional group is a specific group of atoms in a molecule that is responsible for the molecule’s characteristic chemical reactions and properties.
