An organic compound containing at least one halogen.
Chemical compounds that consist of alkanes that have one or more halogens. Haloalkanes undergo nucleophilic substitution because their electronegativity puts a partial positive charge on the α carbon atom. In substitution (RX) reaction the Halogen which is represented as (X) is replaces by another substituent (Y). (R) which is the alkyl group is not changed in the reaction.
