उत्तर
(i) Ethylidene chloride
(iii) Methylene chloride
Explanation:
Gem-dihalides are those dihalides in which two halogen atoms are bonded to the same carbon atom.
(i) \[\ce{\underset{Ethylidene chloride}{Cl2 - CH - CH3}}\]
(ii) \[\ce{\underset{Ethylene dichloride}{Cl - H2C - CH2 - Cl}}\]
(iii) \[\ce{\underset{Methylene chloride}{CH2Cl2}}\]
(iv)

Benzyl chloride
So, in (i) and (iii) two halogen atoms are present on the same carbon atom and they are termed gem-dihalides.
