In chemistry, A radical (also called a free radical) is an atom, molecule, or ion that has an unpaired electron in its outer shell. Because of this unpaired electron, radicals are usually highly reactive and can initiate chemical reactions.
Types of Radicals (Brief Explanation):
Radicals can be classified based on their origin or structure:
Primary Radical
The unpaired electron is on a carbon atom that is attached to only one other carbon atom.
Example: CH3 (methyl radical)Secondary Radical
The carbon with the unpaired electron is attached to two other carbon atoms.
Example: CH3–CH–CH3
Tertiary Radical
The unpaired electron is on a carbon attached to three other carbon atoms.
Example: (CH3)3CAlkyl Radicals
Derived from alkanes by removing one hydrogen atom.
Example: Methyl radical CH3, Ethyl radical C2H5Aryl Radicals
Formed from aromatic rings, like benzene, by removing one hydrogen atom.
Example: Phenyl radical C6H5
Oxygen-containing Radicals
Includes radicals like hydroxyl radical (OH) and peroxyl radical (ROO).
Common in biological and atmospheric processes.
