Explain the difference in physical properties of the polyesters- nylon, phthalic anhydride + ethylen glycol, and...
In Organic Chemistry for the Preparation and Properties of Polymers Lab (using toluene, styrene, benzoyl peroxide, methanol, adipoyl chloride, cyclohexane, hexanediamine, sodium hydroxide, phthalic anhydride, sodium acetate, and ethylene glycol), please help answer the following question; 1. The observation between the two heated polyesters were different. What structural features account for the differences observed? (test tube 1 contained phthalic anhydride, sodium acetate and ethylene glycol and the second test tube contained phthalic anhydride, sodium acetate and glycerol.)
Draw a mechanism for an esterification reaction between phthalic anhydride and ethylene glycol under acidic conditions. (I need help seeing how this reaction would occur with a molecule such as phthalic anhydride, thanks!)
Pre-Lab Preparation es preparing your lab report as outlined in the Laboratory Information section, famil- iarize yourself with temperature control of reactions (see the Laboratory Techni and the safety 3-1). Also answer the following questions: information for the chemicals that will be used in this experiment (Table hat is the role of benzoyl peroxide in the polymerization of styrene? Show the mech- anism for the formation of polystyrene to support your answer Explain the difference between the polyesters synthesized using...
Questions for Experiment 8: Preparation and Properties of Polymers - Polyester and Nylon 1. Which polyester should be theoretically more rigid, the one obtained from ethylene glycol or the one from glycerol? Why? Explain with structural arguments. 2. Draw the structure for the polymer produced from the monomer vinylidene chloride CH-00) 3. Draw the structure of the copolymer produced from vinyl acetate and vinyl chloride. This copolymer is employed in some paints, adhesives, and paper coatings 00CH, CI coc Vinyl...
What physical property of the triethylene glycol solvent facilitates the rate of the reaction? Explain.
#3) Describe the difference between chemical and physical properties and changes of matter? How do these physical and chemical properties relate to intrinsic and extrinsic properties? How are these properties related to the different states of matter? Lastly, how might one classify these different types of matter? Make sure to provide examples of each.
