Question

Haloalkane in the presence of alcoholic KOH undergoes ?

Answer 1

Haloalkanes undergo elimination of hydrogen halide (HX) when boiled with alcoholic solution of potassium hydroxide, resulting in the formation of alkenes. As the hydrogen atom present at b-position of haloalkane (i.e., on the carbon atom next to the one carrying the halogen) is removed, these are called b-elimination reactions or 'dehydro halogenation reactions' (removal of hydrogen halide).
