Interpretation Introduction

Interpretation:

The majororganic product formed by the addition of HBr to the given alkenesin the presence and absence of peroxides is to be identified.

Concept Introduction:
>
Addition of hydrogen halides to alkenes produces alkyl halides.
>
This addition may be electrophilic which proceeds through the formation of carbocation intermediates.
>
During electrophilic addition, a proton is added to the double bond such that the more stable carbocation is produced.
>
The overall addition is according to the Markovnikov rule. The hydrogen atoms get added to the carbon atom which has more hydrogens attached to it.
>
The addition of hydrogen halides to alkenes may be through the formation of free radicals as intermediates.
>
During free radical addition, the bromine is added to the double bond such that a more stable alkyl free radical is produced.
>
The overall addition takes place with a regioselectivity opposite to that of Markovnikov rule: The hydrogen atoms get added to the carbon atom which has less hydrogens attached to it.
