An alkane with a molecular formula `C_(6)H_(14)` reacts with chlorine in the presence of light and heat to give two constitutionally isomeric monochlorides of molecular formula `C_(6)H_(13)Cl`. What is the most reasonable starting alkane ?

Options

A. n-Hexane
B. 2, 2-Dimethylbutane
C. 2, 3-Dimethylbutane
D. 3-Methylpentane

Answer

C

Explanation

`CH_(3) - underset(CH_(3))underset(|)(CH) - underset(CH_(3))underset(|)(CH) - CH_(3) overset(Cl_(2))rarr CH_(3)underset(CH_(2)Cl)underset(|)(CH) - overset(CH_(3))overset(|)(CH) - CH_(3) + CH_(3) = underset(CH_(3))underset(|)(CH) - underset(CH_(3))underset(|)(CH) - CH_(2)Cl`
