The reaction mechanisms that show the formation of poly(ethylene oxide) from ethylene oxide by taking ( H 3 O + ) as an acid and ( OH − ) as a base is to be determined. Concept Introduction: Polymerization is the process that consists linkage of smaller molecular together into a large unit that called as a polymer . These smaller molecules then after called as a monomer of that polymer. Generally, there are two types of polymerization: > Anionic polymerization: This polymerization is taken place due to the action of nucleophiles on an electron deficient site of the given monomer. This polymerization occurs in three steps, initiation, propagation and termination. > Cationic polymerization This polymerization is taken place due to the action of electrophiles on an electron rich site of the given monomer. Thispolymerization occurs in three steps, initiation, propagation and termination.

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.

20. The Brusselator. This hypothetical system was first proposed by a group work- ing in Brussels [see Prigogine and Lefever (1968)] in connection with spatially nonuniform chemical patterns. Because certain steps involve trimolecular reac tions, it is not a model of any real chemical system but rather a prototype that has been studied extensively. The reaction steps are A-X. B+X-Y+D. 2X+ Y-3X, X-E. 305 It is assumed that concentrations of A, B, D, and E are kept artificially con stant so that only X and Y vary with time. (a) Show that if all rate constants are chosen appropriately, the equations de scribing a Brusselator are: dt A-(B+ 1)x + x²y, dy =Bx-x²y. di
