The IUPAC name of ethylidene chloride is:
- 1-Chloroethene
- 1-Chloroethyne
- 1, 2-Dichloroethane
- 1, 1-Dichloroethane
The Correct Option is D
Solution and Explanation
Ethylidene chloride is \(CH_3 – CHCl_2\), its IUPAC name is 1,1-Dichloromethane.
So, the correct option is (D).

Haloalkanes and Haloarenes - Nomenclature
Nomenclature of Haloalkanes:
‘Alkyl halide’ is the very common name for haloalkanes. The written format for haloalkane in the IUPAC name is “numerical position-alphabetically placed halo- root-word-ane”
Nomenclature of Haloarenes:
‘Aryl Halide’ is the very common name for haloarenes. In the nomenclature system, the numerical prefixes are named, depending on the basic position of the halogen atom in the aromatic ring.
In presence of more than one halogen atom, the halogen group is named and the aromatic ring is numbered based on the numerical position of the aromatic ring. Numerical prefixes are written in the format (1, 2) ; (1,3) ; (1,4). Always the least number is given to the halogen number.
