Alcoholic KOH dissociates in water to give RO- ions which is a strong base. It abstracts hydrogen, giving rise to elimination in reaction. We generally use alcoholic KOH to form Alkene from Alkyl Halides, whereas aqueous KOH is used to form alcohols from Alkyl Halides. Alcoholic KOH is used for dehydrohalogenation.
Alcoholic, KOH , specially in ethylene alcohol, produce C2H5O- ions. These ions are stronger base than OH- ion. Thus they abstracts the ß-hydrogen of alkyl halide to produce alkenes. This reaction is known as elimination reaction.
