Quizplus · Accepted Answer

The most reactive alkene in the Heck reaction is the one with the least steric hindrance. In this case, alkene II has the least amount of steric hindrance due to its linear structure compared to the other alkenes which have bulkier groups attached to the double bond. Therefore, alkene II is the best choice for the Heck reaction.
