In the experiment of synthesizing isopentyl acetate by reacting an excess of acetic acid with Isopentyl alcohol and using sulfuric acid as the catalyst, what was the purpose of doing a distillation after heating under reflux for an hour?
1. The reaction mixture contains isopentyl acetate, isopentyl alcohol, water, acetic acid and sulfuric acid. a) Why is the reaction mixture extracted with sodium bicarbonate? In other words, what two substances does sodium bicarbonate react with in the reaction mixture and why are these reactions useful? (4 pts) b) Write a balanced chemical equation for each reaction involving sodium bicarbonate. c) When the reaction mixture is extracted with sodium bicarbonate solution, what substances will be in the aqueous layer? What...
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
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....
If the yield from the reaction of acetic acid with isopentyl alcohol is 45%, how many grams of isopentyl acetate are formed from 3.58 g of acetic acid and 4.70 g of isopentyl alcohol? The reaction is: CH3CO2H+C5H12O→C7H14O2+H2O Express your answer using two significant figures.

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...
