The mechanism would be addition of double bond. Since it's in non-polar solvent, two bromides with attach. Enantiomers will also be formed.
Work Step by Step
The addition of halogens reactions will occurs with the following mechanism. 1) Electrophilic attack forms a bromonium ion. 2) Bromide ion opens the bromonium ion. Since the bromonium ion could form on the either side, the enantiomers will be formed in equal amounts.
