(a) Gem dihalides :
(i) The term gem has derived from geminal meaning for same position.
(ii) The two similar halogen atoms are attached to same carbon atom e.g.
CH3CHX2 ethylidene dihalide or 1, 1-dihaloehtane
CH3CH2CHX2 propylidene dihalide or 1, 1-dihalopropane
isopropylidene dihalide or 2, 2-dihalopropane
actually it is just a process of naming them. there is no thing like reason for this nomenclature.
just that hallide is given prefernce and alkyl group acting as attached group...and dene showing double bonding,
