A vicinal dihalide is not formed in the reaction-

Dihalides

Gem dihalide is formed by the reaction of alkyne and

How many isomeric vicinal- dihalides are possible for the compound having molecular formula C_(3)H_(6) Cl_(2) ?

In the preparation of alkenes, dehydration of alcohols, dehydrohalogenation of alkyl halides, dehalogenation of vicinal dihalides are called beta -elimination reactions

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.
