What type of reaction would produce CH2(OH)CH(OH)CH2(OH) from vegetable oils? Select one: O hydrolysis O hydrogenation O polymerization O nucleophilic addition

1.Consider the polymerization of the following monomers: H2N- -NH2 CI (a) Draw the repeat unit of the resulting polymer. (b) Identify the two structural units comprising the repeat unit. Aramids are produced using the reaction of a benzene-1,4-diamine and a terephthaloyl dichloride.

This polymer is composed of 2 monomer units: an acid chloride and an amine. In the box below, draw the structure of both monomers. (8-10 C (CH₂)6-C CH₂ 어 H n • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • Do not include lone pairs in your answer. They will not be considered in the grading. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. • Separate structures with + signs from the drop-down menu.

3. Dacron is the brand name for the polymer that is made from ethane-1,2-diol and benzene-1,4-dicarboxylic acid. (a) What type of polymer is Dacron? (b) When the two monomers combine, what type of reaction do they undergo and what molecule is eliminated? (c) What is the name for the linkages that join the monomers together?(d) Draw the monomers and the polymer of the reaction to create Dacron. (Use a condensed structural formula in your answer.) HC-C styrene H-O-C- ethane-1,2-diol I H OH НО. 206 H -C-0-H H benzene-1.4-dicarboxylic acid.

31. Match these molecules with their biological roles. (a) glycogen __ viscosity, lubrication of extracellular secretions (b) starch __ carbohydrate storage in plants (c) trehalose __ transport/storage in insects (d) chitin __ exoskeleton of insects (e) cellulose __ structural component of bacterial cell wall (f) peptidoglycan __ structural component of plant cell walls (g) hyaluronate __ extracellular matrix of animal tissues (h) proteoglycan __ carbohydrate storage in animal liver 32. Explain in molecular terms why humans cannot use cellulose as a nutrient, but goats and cattle can.

Draw the organic products of the reactions

a) What is the functionality of TMP and AA, respectively b)i if you start with 2 mol of TMP and 3 mol of AA, will you be running into a risk forming a cross-linked polyester during polymerization, and why?

5. Terylene can be obtained via the polymerization of the dimethylester of benzene- 1,4-dicarboxylic acid and ethane-1,2-diol. Write the equation for the reaction and determine what small molecules were eliminated during the process.

the reaction C3H6 + H2 = C3H8 is: a) replacement b) additions c) polymerization d) esterification
