The species which can best serve as an initiator for the cationary polymerization is:

In cationic polymerizalion, the initiator is an electrophile that adds to the alkene, causing it to become a cation. The Initiator most often used in cationic polymerization is a lewis acid. Such as BF_(3) or AICI_(3) and in anionic polymerization, the iniliator is a nucleophile that reacts with the alkene to form a propagating site that is an anion. Arrange the following group of monomers of decreasing ability to undergo cationic polymerization
