उत्तर
Ethylidene chloride is a/an gem-dihalide.
Explanation:
gem-dihalides are compounds in which both the halogen atoms are linked with the same carbon atom. They known as alkylidene halides \[\ce{CH3 - CHCl2}\] also. The structure of 'Ethylidene chloride' shows that both halogen atoms are present on same carbon atom.
