Methods of Preparation of Acetylene

Preparation methods 1. From calcium carbide: Ethyne is prepared by calcium carbide with water. CaC₂ + 2H₂O → Ca (OH)₂ + C₂H₂ 2. From vicinal dihalides: Vicinal dihalides on treatment with alcoholic potassium hydroxide undergo, dehydrohalogenation one molecule of hydrogen is eliminated to form alkenyl halide which on treatment with sodalime gives alkyne.
