MCQ
Ethylidene chloride is $a/an.......$
  • A
    vic$-$dihalide
  • B
    vinylic halide
  • ✓
    gem$-$dihalide
  • D
    allylic halide
✓

Answer

Correct option: C.
gem$-$dihalide
Gem$-$dihalides are dihaloalkanes that have two halogen atoms of the same type attached to the same carbon a in a molecule. The common naming system of gem$-$dihalides $($geminal halide$)$ is alkylidene dihalides. Ethylidene dichloride thus is a gem$-$dihalide. The chemical formula of ethylidene dichloride is $\ce{C_3H_6Cl_2}.$
