To give the step by step anionic polymerization mechanism for the formation of carbowax by using NaOH as a catalyst. Concept introduction: Poly (ethylene glycol) is a polyether which is obtained from the anionic polymerization of ethylene oxide (C 2 H 4 O). The anionic polymerization of ethylene oxide is complicated by the association phenomenon and the participation of ion-pair and free ion intermediates in the propagation reactions. Anionic polymerization takes place where the monomer unit have a EWG (elctron withdrawing group). This type of polymerization proceeds with the addition of the nucleophile with the monomer’s double bond. The nucleophile may be hydroxide, cyanide etc. On other hand it can also be initiated by the elctron transfer from the alkali species used as an catalyst. In general there is no termination step. The reaction will continue till all the monomer and the catalyst have been consumed. Anionic polymerization is also called living polymerization as the reaction will again start when the monomer and catalyst is added to it.

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.

For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. ?

Predicting As the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will make a molecule with a new C - C bond as its major product: H₂N O H 1. ? 2. H3O+ If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. 0 If the major products of this reaction won't have a new CC bond, just check the box under the drawing area and leave it blank. فا Explanation Check Click and drag to start drawing a structure.
