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.

Calculate the theoretical and percent yield given: 0.648 g of isopentyl alcohol and 1.58 g of acetic acid. This was found to produce 0.351 g of iso-pentyl acetate + H2O. Acetic acid was in excess. This is a Fischer Esterification problem.

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.)

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...
Ester lab calculations
When you set up the reaction, you placed 7.50 milliliters of isopentyl alcohol into the reaction flask and then added excess acetic acid. If at the end of the experiment, you isolated 6.810 grams of isopentyl acetate, what was your percent yield for the reaction?(use correct number of significant figures) Physical Data for Isopentyl Alcohol:Molecular Weight = 88.15 g/molDensity = 0.8000 g/mLPhysical Data for Isopentyl Acetate:Molecular Weight = 130.19 g/mol
