Esterification is the reaction of a carboxylic acid (RCOOH) with an alcohol (R'OH) to form an ester (RCOOR') with loss of water. Equation [1] is an example of an intermolecular esterification reaction. Equation [2] is an example of an intramolecular esterification reaction, that is, the carboxylic acid and alcohol are contained in the same starting material, forming a cyclic ester as product. The equilibrium constants for both reactions are given. Explain why K is different for these two apparently similar...

5) In the "reverse" of esterification, esters can be hydrolyzed with aqueous NaOH (as shown below). The factors that influence the rate of ester hydrolysis are similar to those that affect the rate of esterification described above in problem #4. The first step in this mechanism is nucleophilic attack of hydroxide on the carbonyl carbon for form a tetrahedral intermediate, followed by loss of the alcohol.

In this experiment, we did a Fischer Esterification using excess acetic acid, isopentyl alcohol, and sulfuric acid to form isopentyl acetate. Then sodium bicarbonate and NaCl were used in the extraction step of the experiment. Is there another method we could have used to calculate percent yield other than using the amount of isopentyl acetate? What are the advantages and disadvantages? (Using GC is not the answer we are looking for.)

CONTEXT So we did an Sn1 reaction in chem lab to convert t-butyl alcohol to t-butyl chloride by the following reaction C4H10O + HCl --> C4H9Cl + H2O We did this by mixing the HCl and the t-butyl alcohol in a separatory funnel, then we collected the organic layer that formed and vacuum distilled the product. QUESTIONS What is something that could cause a low yield in this experiment? we got a 26% yield, I was thinking maybe heating up...
