Using a generic strong Brønsted acid, HA as the initiator, the initiation step and the first two propagation steps for the cationic polymerization of methylpropene (isobutylene) are to be drawn. Concept introduction: In cationic polymerization, the cation is formed by the reaction of alkene with an acid in an electrophilic addition step. Bronsted acid is used to protonate the C=C double bond of the monomer. Propagation occurs when the carbocation of the growing chain undergoes electrophilic addition to another monomer. Cationic polymerization takes place if electron-donating groups are attached to the C = C bond.

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.

A pdf file of your hand drawn, stepwise mechanisms for the reactions. For each reaction in the assignment, you must write each mechanism three times (there are 10 reactions, so 30 mechanisms). (A) do the work on a tablet and save as a pdf., it is expected to write each mechanism out and NOT copy and paste the mechanism after writing it just once. Everything should be drawn out stepwise and every bond that is formed and broken in the process of the reaction, and is expected to see all relevant lone pair electrons and curved arrows.
