Ethene, vinyl chloride, and acrylonitrile do not undergo cationic polymerization while isobutylene gives the same, is to be explained. Concept Introduction: Alkenes also undergo polymerization reaction when treated with strong acids. The growing chains in acid catalyzed polymerization are cations, rather than radicals. A cation is an electron deficient species and its stability order is as follows: 1 o < 2 o < 3 o

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.
