Hi! I was wondering if you could help me figure out (please see attachment): Which is the kinetic product? This is difficult for me to decide because with the bromonium ion, there is no actual carbocation intermediate. If I had used HBr instead of Br2, this would have been easier...a tertiary carbocation is obviously better. Thank you!

well, there would be an allylic and a tertiary carbocation. Which one is better?
