The replacement of hydrogen atom(s) in an aliphatic
or aromatic hydrocarbon by halogen atom(s) results
in the formation of alkyl halide (haloalkane) and aryl
halide (haloarene), respectively Haloalkanes contain
halogen atom(s) attached to the sp3 hybridised carbon
atom of an alkyl group whereas haloarenes contain
halogen atom(s) attached to sp2 hybridised carbon
atom(s) of an aryl group Many halogen containing
organic compounds occur in nature and some of
these are clinically useful These classes of compounds
find wide applications in industry as well as in day-
to-day life
