    Study Notes

    Esterification

    • Esterification is a reaction between a carboxylic acid and an alcohol, catalyzed by a strong mineral acid (e.g., sulfuric acid or hydrochloric acid).
    • The reaction produces an ester and water.

    Mechanism of Esterification

    • The carboxylic acid and alcohol react to form an ester and water.
    • The reaction involves the elimination of water, with the hydrogen from the alcohol and the H from the carboxylic acid combining to form water.

    Acetic Acid and Ethanol Reaction

    • Acetic acid and ethanol react to form ethyl acetate and water.
    • The reaction involves the elimination of water, with the hydrogen from ethanol and the H from acetic acid combining to form water.

    Acetic Acid and Isobutanol Reaction

    • Acetic acid and isobutanol react to form isobutyl acetate and water.
    • The reaction involves the elimination of water, with the hydrogen from isobutanol and the H from acetic acid combining to form water.

    Intramolecular Esterification

    • Intramolecular esterification occurs when a carboxylic acid and an alcohol are part of the same molecule.
    • The reaction forms a cyclic ester (lactone) and water.

    4-Hydroxybutanoic Acid and Methanol Reaction

    • 4-Hydroxybutanoic acid and methanol react to form a cyclic ester (lactone) and water.
    • The reaction involves the elimination of water, with the hydrogen from methanol and the H from 4-hydroxybutanoic acid combining to form water.

    Fischer Esterification

    • Fischer esterification is a type of esterification reaction that occurs between a carboxylic acid and an alcohol, catalyzed by a strong mineral acid.
    • The reaction produces an ester and water.

    Characteristics of Esters

    • Esters have a sweet, fruity smell.
    • Esters are commonly used in perfumes, flavorings, and fragrances.
    • Esters have a lower boiling point than carboxylic acids and alcohols.
