DIHALIDES & MONOHALIDES

BY HYDROLYSIS OF GEM-DIHALIDES

Statement-I: Acetylene is formed when ethylene chloride or ethylidene chloride is heated with alcoholic KOH. Statement-II: Both gem dihalides and vinicinal dihalides on dehydrohalogenation form alkyne.

Vicinal dihalides undergo double dehydrohalogenation to give terminal alkyne. How many moles of NaNH_2 are used in the overall reaction?

Gem dihalides on treatment with alcoholic KOH give
