Halo alkane in the presence of alcoholic KOH undergoes – InterviewSolution

1.	Halo alkane in the presence of alcoholic KOH undergoes
Answer» ELIMINATION polymerisation dimerisation substitution Solution :When an alkyl halide is heated with ALCOHOLIC solution of caustic potash DEHYDROHALOGENATION occurs, a molecule of hydrogen halide is eliminated fromm the adjacent carbon atoms, producing a double BOND. In dehydrohalogenation preferential order for elimination of H is `3^(@) gt 2^(@) gt 1^(@)` (Saytzeff rule).
