The structure of the monomer from which the given polymer is made is to be determined. Concept Introduction: Polymers are materials made of long repeating chain of molecules called monomer units. Based on the modes of polymerization , polymers are classified as follows: Addition polymers – Addition polymers are formed by repeated addition of the monomer units. The monomer units are unsaturated hydrocarbons generally. There is no elimination of molecules in the reaction. Condensation polymers – Condensation polymers are formed by repeated condensation between two different monomer units along with the formation of elimination products like water.

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .

Complete the following table. The only density needed is already given. Show your calculations in a neat and easy-to-follow manner in the space below the table. All units should be included and significant figures should be given close attention. Be sure to notice that the amount of material should be in millimoles rather than moles, and the theoretical mass of the product should in milligrams rather than grams.

Kumada Coupling: 1. m-Diisobutylbenzene below could hypothetically be synthesized by Friedel-Crafts reaction. Write out the reaction with a mechanism and give two reasons why you would NOT get the desired product. Draw the reaction (NOT a mechanism) for a Kumada coupling to produce the molecule above from m-dichlorobenzene. Calculate the theoretical yield for the reaction in question 2 using 1.5 g of p-dichlorobenzene and 3.0 mL isobutyl bromide. What signals appeared/disappeared/shifted that indicate that you have your intended product and not starting material? What other impurities are present in your product and how do you know?
