The detailed mechanism that illustrates the initiation and addition of the first two monomers in the given polymerization reaction is to be drawn. Concept introduction: Polymerization reactions start with the generation of a reactive species from a monomer molecule. The reactive species may be a radical or a carbocation. This reactive species then adds to another molecule of the monomer to form a dimer. At the same time, a radical or a carbocation is generated on the added molecule, which can continue the addition reaction. In the case of acid-catalyzed alkene polymerization, a proton transfer from the acid to a molecule of alkene generates a carbocation reactive species. This in turn acts as an electrophile and adds to the double bond from another monomer molecule, generating a second, dimeric carbocation. This carbocation will then propagate the polymerization reaction.

Answer 1

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.

Just try completing it and it should be straightforward according to the professor and TAs.

The grading is not on correctness, so if you can just get to the correct answers without perfectionism that would be great. They care about the steps and reasoning and that you did something. I asked for an extension, but was denied the extension.
