Functional Groups

Reactive Groups in Organic Chemistry

By

Functional groups are groups of atoms found within molecules that are involved in the chemical reactions characteristic of those molecules. Functional groups can pertain to any molecules, but you will usually hear about them in the context of organic chemistry. The symbol R and R' refer to an attached hydrogen or hydrocarbon side chain or sometimes to any group of atoms.
