Question

Ethylidene chloride is a /an ........

(a) vic-dihalide (b) gem-dihalide (c) allylic halide (d) vinylic halide

Answer 1

Answer: (b) gem-dihalide

In Vic-dihalides, halogen atoms are present on the adjacent carbon atoms.

In gem-dihalides, halogen atoms are present on the same carbon atom. They are known as alkylidene halides. In ethylidene chloride $H_{3}C-CHC{l}_2$ both halogen atoms are present on same carbon atom so it is gem-dihalide.

In allylic halides, the halogen atom is bonded to $s{p}^3$ hybridized carbon atom next to carbon-carbon double bond.

In vinylic halides, the halogen atom is bonded to $s{p}^2$ hybridized carbon atom of a carbon-carbon double bond.
