Illustrated Glossary of Organic Chemistry

Alkyl halide (haloalkane): A functional group characterized by a halogen atom (fluorine, chlorine, bromine, or iodine) bonded to an sp3 carbon atom.

Ethyl fluoride, a typical
primary (1o) alkyl fluoride.
Tert-butyl chloride, a typical
tertiary (3o) alkyl chloride.
2-Bromopropane, a typical
secondary (2o) alkyl bromide.
Iodomethane, a typical
methyl alkyl iodide
Bromobenzene is not an alkyl halide because its halogen atom (bromine) is bonded to an sp2 carbon of a benzene ring.
