What is Functional Group?
A specific group of atoms within a molecule responsible for characteristic chemical reactions of that molecule. Common functional groups include hydroxyl (-OH), carbonyl (C=O), carboxyl (-COOH), amino (-NH₂), and halide (-X). Functional groups determine organic compound reactivity.

Functional group identification is central to organic chemistry, drug design, biochemistry, and materials science. Functional groups are the basis of IUPAC nomenclature and are identified by IR spectroscopy (characteristic stretching frequencies), NMR (chemical shift regions), and mass spectrometry …
Functional groups determine toxicological profile: nitro groups (toxicity, mutagenicity), epoxides (carcinogenicity, alkylating agents), aldehydes (irritants, potential carcinogens), acid chlorides (corrosive, reactive). Identifying functional groups in unknown compounds is essential for safe handli…
