Quizplus · Accepted Answer

Cationic polymerization involves the initiation of a polymer chain through the generation of a cationic species, which then reacts with a monomer to form a new reactive site. Monomers that are electron-rich or have a high degree of unsaturation are most reactive towards cationic polymerization. Option I has a high degree of unsaturation as it is a diene, so it would be the most reactive towards cationic polymerization. Therefore, Option A) I is the best choice for the most reactive monomer.
