Thank you in advance!
Homework Answers
1) H2SO4 is a catalyst and a dehydrating agent. If we do not add
H2SO4 to the reaction, the reaction will not proceed.
The ester is washed with bicarbonate solution before distilling
because bicarbonate is a very weak base and neutralizes any acid
present. Thus we can remove added H2SO4 and unreacted carboxylic
acid from the ester.
2. We do not distill the citrus and coconut esters as they have high boiling points. We distill the banana, pear and pineapple ester as they have low boiling points.
3. The IR contains strong and broad peak around 3331 
which
indicates presence of -OH group. This indicates presence of
unreated alcohol in the reaction. Hence, the reaction is incomplete
and the product ester is impure.

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...

This is a Fischer Esterification using the alcohol, methanol,
and the carboxylic acid, butyric acid, to create the ester, methyl
butanoate (smells like apple). After refluxing methanol, butyric
acid, and concentrated sulfuric acid, a separatory flask was used
and the ester was extracted using ice water, then diethyl ether,
then 2 portions of sodium carbonate, and a saturated sodium
chloride brine solution. Anyhydrous sodium sulfate was used after
separation to dry the ester. Please help!!

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.)
