Consider propanoic acid and pentanoic acid and the corresponding alcohols with the same number of carbons, propanol and pentanol. Which is more soluble in water, the alcohol or the carboxylic acid? Why? [you should have two selections.]
a. Propanoic acid and pentanoic acid are more soluble in water than the corresponding alcohol
b. The solubility of carboxylic acids in water decreases with increasing chain length.
c. Propanol and pentanol are more soluble in water than the corresponding carboxylic acid
d. The solubility of alcohols in water decreases with increasing chain length.
Alcohols are generally more soluble in water than carboxylic acids of the same chain length because of increased hydrogen bonding with the -COH functional group.
e. Carboxylic acids are generally more soluble in water than alcohols of the same chain length because of increased hydrogen bonding with the -COOH functional group.
Write the chemical equation for a pentanoate ion acting as base when it reacts with hydrochloric acid (HCI).

- Esterication is the reaction of a carboxylic acid (RCOOH) with an alcohol (R'OH) to form an ester (RCOOR') with loss of water. Equation [1] is an example of an intermolecular esterication reaction. Equation [2] is an example of an intramolecular esterication reaction; that is, the carboxylic acid and alcohol are contained in the same starting material, forming a cyclic ester as product. The equilibrium constants for both reactions are given.
