    Study Notes

    Carboxylic Acid Derivatives

    • Carboxylic acid derivatives can convert into carboxylic acids or related derivatives.
    • All derivatives have a carbonyl carbon located at carbon number 1.

    Nomenclature of Carboxylic Acid Derivatives

    • Carboxylic Acid: Suffix is -oic acid
    • Acid Chloride: Suffix is -oyl chloride
    • Acid Anhydride: Suffix is -oic anhydride
    • Ester: Suffix is -oate
    • Amide: Suffix is -amide
    • Nitrile: Suffix is -nitrile

    Carboxylic Acids

    • Contain a carboxyl group (-COOH).
    • Named with the suffix -oic acid, with the carbonyl carbon not included in the name.
    • Example: Propanoic acid (common name: propionic acid).

    Acid Chlorides

    • Feature a carbonyl group bonded to a chlorine atom.
    • Named with the suffix -oyl chloride.
    • Example: Propanoyl chloride.

    Acid Anhydrides

    • Comprise two carboxyl groups bonded together.
    • Named using the suffix -oic anhydride.
    • In symmetrical anhydrides, the name simplifies to one carboxylic acid name.
    • Example: Butenoic propanoic anhydride (asymmetrical), propanoic anhydride (symmetrical).

    Esters

    • Formed when a carboxyl group is bonded to an alkyl group.
    • Suffix is -oate; base name derives from the carboxylic acid, not the alcohol.
    • Example: Ethyl 3-methylbutanoate.

    Amides

    • Comprised of a carboxyl group bonded to an amino group.
    • Suffix is -amide; nitrogen substituents indicated by a capital N.
    • Example: N-methylpropanamide.

    Nitriles

    • Feature a carboxyl group bonded to a cyano group.
    • Suffix is -nitrile; nitrile carbon included in the longest carbon chain.
    • Example: Propanenitrile.

    Physical Properties of Carboxylic Acids

    • Display higher boiling points than anticipated due to dimerization and hydrogen bonding.
    • Dimerization effectively doubles molecular size, enhancing van der Waals forces and boiling point.

    Overview of Carboxylic Acid Derivatives

    • Carboxylic acid derivatives can convert into carboxylic acids or other derivatives.
    • All derivatives feature a carbonyl carbon at carbon number 1.

    Nomenclature of Carboxylic Acid Derivatives

    • Carboxylic Acid: Suffix -oic acid
    • Acid Chloride: Suffix -oyl chloride
    • Acid Anhydride: Suffix -oic anhydride
    • Ester: Suffix -oate
    • Amide: Suffix -amide
    • Nitrile: Suffix -nitrile

    Carboxylic Acids

    • Comprised of a carboxyl group (-COOH).
    • Named with the suffix -oic acid and the carbonyl carbon is not numbered in the name.
    • Example: Propanoic acid (also known as propionic acid).

    Acid Chlorides

    • Contains a carbonyl group bonded to a chlorine atom.
    • Denoted by the suffix -oyl chloride.
    • Example: Propanoyl chloride.

    Acid Anhydrides

    • Comprise two carboxyl groups bonded together.
    • Named with the suffix -oic anhydride.
    • For symmetrical anhydrides, the name includes only one carboxylic acid name.
    • Examples: Asymmetrical - butenoic propanoic anhydride; Symmetrical - propanoic anhydride.

    Esters

    • Feature a carboxyl group linked to an alkyl group.
    • Named with the suffix -oate, based on the carboxylic acid rather than the alcohol.
    • Example: Ethyl 3-methylbutanoate.

    Amides

    • Contain a carboxyl group bonded to an amino group.
    • Indicated by the suffix -amide.
    • If nitrogen has substituents, they are represented with a capital N.
    • Example: N-methylpropanamide.

    Nitriles

    • Contain a carboxyl group bonded to a cyano group.
    • Suffix used is -nitrile.
    • The carbon of the nitrile is counted in the longest carbon chain.
    • Example: Propanenitrile.

    Physical Properties of Carboxylic Acids

    • Higher boiling points than expected due to dimerization and intermolecular hydrogen bonding.
    • Dimerization increases molecular size, enhancing van der Waals forces and raising boiling points.
