An alkyl chloride produces a single alkene when it reacts with sodium ethoxide and ethanol . This alkene on hydrogenation produces 2-Methylbutane. What is the identity of the alkyl halide ?

Options

A. 1-Bromo-2,2-dimethylpropane
B. 1-Bromobutane
C. 1-Bromo-2-methylbutane
D. 2-Bromo-2-methylbutane

Answer

C

Explanation

`underset("1-Bromo-2-methylbutane")(CH_(3)CH_(2)-overset(CH_(3))overset(|)(C)H-CH_(2)Br) overset(C_(2)H_(5)ON a//C_(2)H_(5)OH)to CH_(3)CH_(2)-overset(CH_(3))overset(|)(C)=CH_(2) overset(H_(2)//"catalyst")to underset("2-Methylbutane")(CH_(3)CH_(2)-overset(CH_(3))overset(|)(C)H-CH_(3))`
