Answer
HBr and HOOR can be used to synthesize the product.
Work Step by Step
The mechanism is:
Initiation: Formation of bromine radicals.
Propagation: A radical reacts to generate another radical.
Step 1: A bromine radical adds to the double bond to generate an alkyl radical on the more substituted carbon atom.
Step 2: The alkyl radical abstracts a hydrogen atom from HBr to generate the product and a bromine radical.
The bromine radical generated in Step 2 goes on to react with another molecule of alkene in Step 1, continuing the chain.
