Which product is formed by the chlorination of 2-methyl-1-butene?

Question

Quizplus · Accepted Answer

When 2-methyl-1-butene is chlorinated, chlorine adds across the double bond to form a mixture of cis and trans-2-chloro-2-methylbutenes. Further chlorination leads to the formation of 1,2-dichloro-2-methylbutane as the major product. 1,1-dichloro-2-methylbutane is not formed because the chlorine cannot add to a tertiary carbon. 2-chloro-2-methylbutane is also not formed because the chlorine cannot add to one of the methyl groups. 1-chloro-2-methylbutane is a minor product but not the major product.
