(xii) o-Br-C6H4CH(CH3)CH2CH3CH3


(i) 2-chloro-3-methylbutane, (2 alkyl halide)


Explanation: The Cl atom is attached with two alkyl groups therefore 2 alkyl halide.


(ii) 3-chloro-4-methylhexane (2 alkyl halide)


Explanation: The Cl atom is attached with two alkyl groups therefore 2 alkyl halide.


(iii) 1-iodo-2,2-dimethylbutane (1 alkyl halide)


Explanation: The atom I is attached with one alkyl group therefore 1 alkyl halide.


(iv) 1-bromo-3,3-dimethyl-1-phenylbutane (2 benzylic halide)


Explanation: The atom Br is attached with two alkyl groups with the benzene group therefore 2 benzylic halide.


(v) 2-bromo-3-methylbutane (2 alkyl halide)


Explanation: The atom Br is attached with two alkyl groups therefore 2 alkyl halide.


(vi) 1-bromo-2-ethyl-2-methylbutane (1 alkyl halide)


Explanation: The atom Br is attached with one alkyl group therefore 1 alkyl halide.)


(vii) 3-chloro-3-methylpentane (3 alkyl halide)


Explanation: The atom Cl is attached with three alkyl groups therefore 3 alkyl halide.


(viii) 3-chloro-5-methylhex-2-ene (vinylic halide)


Explanation: The atom Cl is attached with the double bond i.e. at vinyllic position vinylic halide.)


(ix) 4-bromo-4-methylpent-2-ene (allylic halide)


Explanation: The Br atom is attached with the carbon next to the double bond i.e. at allylic position therefore allylic halide.


(x) 1-chloro-4-(2-methylpropyl)benzene (aryl halide)


Explanation: The Cl atom is attached with the benzene i.e. at aryl position therefore aryl halide.


(xi) 1-chloro-3-(2,2-dimethylpropyl)benzene (1 benzylic halide)


Explanation: The Cl is attached with one alkyl group at the benzene carbon therefore 1 benzylic halide.


(xii) 1-bromo-2-(1-methylpropyl)benzene (aryl halide)


Explanation: The Br is attached with the benzene i.e. at aryl position therefore aryl halide.
