Cationic polymerization

Describe briefly: Anionic polymerization

Describe briefly: Radical polymerization

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

Which of the following alkenes is most reactive towards cationic polymerization?

Name the chief ore of aluminium. Describe briefly the extraction of aluminium from this ore.

Describe briefly the ionic concept of oxidation and reduction. Give an equation to illustrate.

Describe briefly (a) Catalytic converter (b) Defunct ships (c) e-wastes.

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