Expert Answer
Dear Student
1. By dehydrohalogenation of haloalkanes
Haloalkanes on heating with alcoholic pottassium hydroxide, loses one molecule of hydrogen halide to give alkene.
2. Dehalogenation of vicinal dihalides
The vicinal dihalides undergo elimination reaction in the presence of Zn, and form alkene.
