The reaction of HBr with 1-propene in the presence of peroxides will produce primarily

Options

A. 2-bromopropane
B. 1-bromopropane
C. 2-bromopropene
D. 1.2-dibromopropane

Answer

B

Explanation

Markovanikov's rule predicts that in the absence of peroxides the addition of hydrogen halide across a double bond will occur with hydrogen being added to the carbon, which already contains the most hydrogen. In the presence of peroxides , however , a free radical mechanism results in hydrogen bromide being added in the opposite orientation.
