Para-methoxystyrene undergoes cationic polymerization more rapidly than meta-methoxystyrene need to be explained. Concept introduction: Polymerization is a reaction when monomer molecules are reacted to form a polymer chain. Polymerization can occur via three ways, Cationic polymerization Radical polymerization Anionic polymerization Cationic polymerization is the polymerization of the monomer (vinyl) with strong electron donating groups . In this method cationic initiator transfers charge to the monomer which becomes active and further propagates with another molecules. If the electron donating group is present in the ortho or para position it stabilizes the formed positive charge than the same group present in meta position. Anionic polymerization is the polymerization of the monomer (vinyl) with strong electron-withdrawing groups (electronegative groups). In this polymerization carbanion is the active species. Radical polymerization is a type of polymerization where the reaction occurs by successive addition of free-radicals.

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.

2) (4 pt) After the reaction was completed, the student collected the following data. Crude product data is the data collected after the reaction is finished, but before the product is purified. "Pure" product data is the data collected after attempted purification using recrystallization. Student B's data: Crude product data "Pure" product data after recrystallization Crude mass: 0.93 g grey solid Crude mp: 96-106 °C Crude % yield: Pure mass: 0.39 g white solid Pure mp: 111-113 °C Pure % yield: a) Calculate the crude and pure percent yields for the student's reaction. b) Summarize what is indicated by the crude and pure melting points.
