A B C D E C No, this would be a minor product corresponding to a 1,2-addition which occurs at low temperatures (i.e. it is the kinetic product). No, this would be a minor product corresponding to a 1,2-addition which occurs at low temperatures (i.e. it is the kinetic product). Correct, the intermediate carbocation is a 3o and stabilized by the allylic system (i.e. a 1,4-addition and corresponds to the thermodynamic product). No, this has the wrong regiochemistry for the addition as it would have reacted via a 2o carbocation rather than a 3o carbocation, and it does not occur in an anti-Markovnikov mechanism. No, this is a minor product corresponding to two 1,2-additions. Review Carey 5th Ed. Chapter 10 section 10
