acetic acid is 25 ml and alcohol is 20 ml
The synthesis of an ester by the reaction of a carboxylic with an alcohol is an equilibrium reaction. H - R-OH HO ROH R OR, Recall from general chemistry that, according to Le Caiclista principle, an equilibrium can be shifted toward greater product formation by using an excess of reactant or by removal of a reaction product as it forms. 1. Are any products removed during the reaction period (the...

what is my limiting reagent, theoretical yield

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.

EXPERIMENT 20 CSI: SMU Part 2. Synthesis of an Ester. Esters are compounds of the form RCOOR'. They occur naturally in many plants and animals, and can be synthesized. They have a pleasant aroma usually described as "fruity of flowery".
