Interpretation Introduction

Interpretation:

Stereoisomers formed from the given hydrobromination reaction have to be given and also the relationship between those two isomers has to be given.

Concept Introduction:

Radical hydrobromination reaction:

Under photochemical condition $\text{HBr}$ gives hydrogen and bromine radical.  Alkene react with bromine radical and forms the more stable radical then hydrogen radical abstracted by the alkyl radical and produces the final product.

General mechanism for this reaction is illustrated below,
