Interpretation:
The method other than addition of excess of acetic acid needs to be explained that favors the formation of ester in the preparation of isopentyl acetate.
Concept Introduction:
Ester is an organic compound with the general formula RCOOR. It can be formed by the reaction of
Answer to Problem 1Q
Another method of involving right-hand side of the equation that will favor the formation of ester from acetic acid and isopentyl alcohol is removal of one of the product that is water.
Explanation of Solution
The reaction for the formation of isopentyl acetate is as given below:
According to Le Chatelier's principle, if the equilibrium reaction is subjected to any change in the concentration, temperature or pressure, the reaction always moves in that direction that can reduce the effect of change. If water is removed in the given reaction, the equilibrium will move towards right side to form more products.
Another method of involving right-hand side of the equation that will favor the formation of ester from acetic acid and isopentyl alcohol is removal of one of the product that is water.

- State True or False for each of the following: .Esters can be formed by via a dehydration reaction between an acohol and a carboxylic acid. True False 2. The midpoint of a titration occurs at pH values corresponding to a particular proton's pKa. True False 3. pH and pKa are interchangeable because they measure the same thing. True False 4. When preparing an ester using an acid chloride, you are still forming the same C-O bond on the ester product as in an acid-catalyzed esterification. True False 5. Acid anhydrides are more reactive towards alcohols than the corresponding acid chloride. True False 6.Water is a stronger acid than phenol. True False 7.
