Can you answer these questions based on the Synthesis of Nylon-6,6 using adipoyl chloride and 1,6-hexanediamine Discuss the polycondensation reaction. Why would water interfere with it? In case experiment failed-explanation is expected. Why it failed? What could be improved. Explain molecular structure vs signal relationship . In your discussion consider the following concepts: polycondensation, functional groups, fibril formation and stabilization (interchain molecular itneractions) , reaction yield and the role of NaOH solution used in the reaction

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.)

1. Your boss asks you to prepare and then standardize a sodium hydroxide solution, which you do as you did in this lab. The average concentration is 0.1063M. He then hands you a solution of nitric acid and asks you to titrate it with your NaOH solution. It requires 27.33mL of your tandardized NaOH solution to titrate 24.79mL of the nitric acid solution. Write a chemical quation for the neutralization reaction and then calculate the molarity of the nitric...
