what is my limiting reagent, theoretical yield
calculated from moles , and % yield for the synthesis of banana
oil?
Isoamyl acetate (banana oil) is made by the acid
catalyzed reaction (fischer esterification) between isoamyl alcohol
and acetic acid. sulfuric acid was used as the catalyst for the
fast conversion of product from starting alcohol and acid. the
catalyst only affects the rate of the reaction not the extent of
the reaction.
here is the data from lab:

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.)
Solution 1 (starting material): 4.0 mL of concentrated sulfuric acid is added to a flask, 2.0 mL of methyl benzoate is then added to the sulfuric acid solution Solution 2 (electrophile, nitronium ion): 2.0 mL of concentrated nitric acid is added to a test tube, followed by 2.0 mL of concentrated sulfuric acid. Add solution 2 to solution 1. Calculate the theoretical yield. concebtration was not given

What can cause a low percent yield? In lab we did fischer esterification using benzoic acid and methanol to yield methyl benzoate. 3.05 grams of benzoic acid were used and 1.10 grams of methyl benzoate were produced. We also washed the product multiple times with water, 10% sodium bicarbonate solution, then saturated sodium chloride solution. Could the washing cause a low percent yield? If so, can you explain why?
find the theoretical yield of the acetysalicylic acid .
EXPERIMENT 19 PREPARATION OF ASPIRIN In addition to the Fischer esterification method presented in Experiment 18, a second method for preparation of esters involves the reaction of anhydrides with the hydroxyl This method is ospecialy usoful for tho preparation of acetate esters, since acetic anhydride is an inexpensive and reactive reagent. In this experiment the hydroxyl group of salicylic acid is acetic anhydride to make acetylsalicylic acid, or aspirin. The short...
how do I determine %yield and theoretical yield from Fisher esterification reaction? Glacial acetic acid M.W= 60.052 g/mol density=1.05 g/cm used 4.0mL, 70 mmol 3-methyl-1-butanol m.w= 88.148 g/mol density=810 kg/m. used 2.5mL, 23mmol Dowlex-50 used 0.3mL Silica Gel used 0.4mL procedure • Glacial acetic acid (4.0 mL, 70 mmol, 3-methyl-1 butanol (2.5 mL, 23mmol), Dowex-50 (0.3 and silica gel (0.4 g) are added to a microwave vessel • A stir bar is added • The vessel is filled with a...
Calculate theoretical and percent yield. In this experiment, salicylic acid and acetic anhydride will be reacted to form acetylsalicylic acid in an acid catalyzed reaction. In a reaction tube, add approx. 140 mg salicylic acid, a boiling chip and a small drop of 85% phosphoric acid. Add 0.3mL acetic anhydride, which should wash the reactants to the bottom of the tube. Mix thoroughly. Heat in a beaker of water at 90oC for 5 min. Cautiously add 0.2 mL water to...
