The reaction is Esterification
Acetic Acid + isoamyl alcohol yielding isoamyl acetate
During the extraction indicate which substance(s) is (are)) removed at each step with the following reagents:
a. washing with water
b. washing with saturated sodium bicarbonate.
Since the reaction you will perform is reversible, give two ways you could push the equilibrium in the forward direction in the laboratory.

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.)

This experiment involved the use of Fischer Esterification to create isopentyl acetate from reacting isopentyl alcohol with acetic acid and sufluric acid. 1. Provide a balanced equation to explain the evolution of gas during the sodium bicarbonate washing step. 2. The microscale synthesis of esters often uses a Dean-Stark trap. A Dean-Stark trap separates and collects water during a reaction. How would using a Dean-Stark trap during a Fisher-Esterification affect the synthesis? 3. Esters are often used in artificial flavorings....

Assume you are doing an experiment on the esterification of isopentyl acetate using 1mL of isopentyl alcohol and 1.5mL of acetic acid. Assuming complete reaction, calculate the amount of acetic acid left in the post-reaction mixture at the end of reflux Calculate the amount of 5% aq sodium bicarbonate needed to neutralize the unreacted acetic acid
Since the reaction you wil perform is reversible, give two ways you could push the equilibrium in the forward direction in the laboratory.
