Preparation of SyntheticBanana Oil Lab: synthesize isopentyl acetate by combiningisopentyl alcohol with acetic acid and sulfuric acid under refluxfor an hour So
Describe and explain how each of the folllowing experimentalerrors or variations might affect your results:
a) You failed to dry the reaction flask after washing it withwater
b) You forgot to add the sulfuric acid
c) You used twice the amount of acetic acid specified in theprocedure
d) You left out the sodium bicarbonate washing step
e) Thermometer bulb was 1cm higher than it should have been
Calculate the amount of isopentyl acetate that should be present in the reaction mixture at equilibrium based on 300 mmol of acetic acid and 150 mmol of isopentyl alcohol as starting quantities. Use equilibrium constant of 4.2 for this calculation. Moles can be used in place of concentration as volumes cancel out.
Determine the order of the reaction and write a narrative of your approach to determine its order. What is the rate constant for the reaction?
