    reagent used in dehydrohalogenation is ALCOHOLIC KOH or ALCOHOLIC NaOH.

    Dehydrohalogenation involves formation of alkene from an alkyl halide by removal of halide atom and one hydrogen atom using alcoholic KOH or alcoholic NaOH


    CH3CH2X -----(alc. KOH or NaOH)------ CH2 = CH2 + HX

    where X is halogen atom

    CH2=CH2 is alkene


    it is a 1,2- elimination reaction

    The base extracts one hydrogen atom from the carbon atom adjacent to the carbon atom having the halogen atom thereby resulting in the formation of a double bond between the two carbon atoms.

    it is a second order reaction

    H and X should be anti-coplanar for this reaction to take place
