In Organic Chemistry II for the 'Preparation and Properties of Soap' lab, please help answer the following questions; 1. Write out a step-by-step mechanism for saponification. You may begin with a simple ester such as ethyl acetate. 2. The experimental procedure directs you to generously lubricate (grease) the ground glass connection between the 10 ml r.b flask in which saponification is being carried out and the reflux condenser. Why is this generous lubrication needed?

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.)

Phosphorus pentachloride, PCl5, an important reagent in organic chemistry for converting alcohols to alkyl chlorides (ROH ---> RCl), is hydrolyzed in water to form phosphoric acid and hydrogen chloride. In the gaseous state, however, PCl5 can decompose at 250oC according to the following reaction PCl5(g) <---> PCl3(g) + Cl2(g), for which K = 0.0240 If a 2500.-L vessel containing 3250. kg of PCl3(g) with a constant chlorine pressure of 3.525 atm is allowed to reach equilibrium, how many kilograms of...
