In Synthesis of Isopentyl Acetate experiment, how was the acetic acid and sulfuric acid neutralized after reflux has been completed? Write two separate balanced chemical equations that show how each acid was neutralized in this experiment. Isopentyl alcohol + acetic acid -> isopentyl acetate + water The reaction is treated with concentrated Sulfuric acid

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.)

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

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....

We made esters from carboxylic acids and alcohol. (for one of them, acetic acid + isopentyl alcohol + couple drops of sulfuric acid). Could someone please explain those. Thank you 1. Consider if we had prepared high molecular weight esters, what problems would this pose regarding our method of analysis 2. We used sulfuric acid as a catalyst, but carboxylic acids are a reagent in this reaction. Would simply using excess carboxylic acid work as efficiently as sulfuric acid to...
