An alkane with a molecular formula of C6H14 reacts with chlorine in the presence of light and heat. Two constitutionally isomeric monochlorides of molecular formula C6H13Cl are formed (along with a mixture of dichlorides, trichlorides, etc.). What is the most reasonable structure for the starting alkane?
a. CH3CH2CH2CH2CH2CH3
b. (CH3)2CHCH2CH2CH3
c. CH3CH(CH2CH3)2
d. (CH3)3CCH2CH3
e. (CH3)2CHCH(CH3)2
