Open in App
Solution
The correct option is D n−propyl bromide
CH3CH=CH2+HBrperoxides−−−−−−→CH3CH2CH2Br
Hydrogen Halides like HBr usually react with alkenes using an electrophilic addition mechanism.
However, in the presence of organic peroxides, HBr adds to the carbon across the double bond which carries a lesser number of hydrogen atoms. This is called Anti-Markownikoff's rule.
This is called peroxide effect or Anti-Markovnikovs rule.
