This class includes
(a) Alkyl halides or haloalkanes (R—X)
In alkyl halides, the halogen atom is bonded to an alkyl group (R) They form a homologous series represented by CnH2n+1X They are
further classified as primary, secondary or tertiary according to the
nature of carbon to which halogen is attached If halogen is attached to
a primary carbon atom in an alkyl halide, the alkyl halide is called
primary alkyl halide or 1° alkyl halide
