Compounds derived from hydrocarbons by replacing one or more hydrogen atoms with halogen atoms are known as halogen derivatives. The halogen derivatives of alkanes are known as alkyl halides or haloalkanes. In contrast, the halogen derivatives of arenes are known as aryl halides or haloarenes, respectively.
