Identify whether the given pair of monomers form chain-growth or step-growth polymers . Concept introduction: Polymers can be classified as chain-growth and step-growth polymers. Chain-growth polymers are the one which are formed when monomer is added to the other monomer growing chain one at a time. This growing polymer chain usually has only one reactive site. This site is called growth point. Step-growth polymers are the one when the monomers react with each other to form oligomers. These oligomers are joined together to form polymers. This usually occurs when bifunctional monomers are used. This has got two growth points. To identify : whether the monomers used to form chain-growth or step-growth polymer.

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.
