MHT CET Chemistry question

An alkyl bromide produces a single alkene when it reacts with alcoholic KOH. This alkene on hydrogenation produces 2-methylbutane. Identify the alkyl halide.

(A)1-Bromo-2,2-dimethyl propane
(B)1-Bromobutane
(C)1-Bromo-2-methylbutaneCorrect
(D)2-Bromo-2-methylbutane

Answer: (C)

Solution

1-Bromo-2-methylbutane, , has only one β-carbon, so alcoholic KOH gives the single alkene 2-methylbut-1-ene, whose hydrogenation yields 2-methylbutane.
