Calculate the amount of isopentyl acetate that should be present in the reaction

Question

Calculate the amount of isopentyl acetate that should be present in the reaction mixture at equilibrium, based on the quantities of starting materials you used and a value of 4.2 for the equilibrium constant. b) Estimate the mass of isopentyl acetate that was lost (1) as a result of incomplete reaction, (2) during the washings, and (3) during the distillation. Assume that the ester's solubility in aqueous NaHCO3 is about the same as in water. Compare the sum of these estimated losses with your actual product loss.

Explanation / Answer

calculated assuming the reaction was irreversible and there was 100% yield) and multiplied it by (4.2/5.2), as I assumed an equlibrium constant of 4.2 means there are 4.2 moles of products for every 1 mole of reactants at equilibrium. I came up with this:

19.53 grams expected yield * 4.2/5.2 = 15.77 grams true expected yield
