    Study Notes

    Alcohols

    • Contain an -OH (hydroxyl) group bonded to a tetrahedral carbon atom.
    • Classified as primary (1°), secondary (2°), and tertiary (3°) based on the number of carbon atoms bonded to the carbon bearing the -OH group.

    Aldehydes

    • Contain a carbonyl group (C=O) bonded to a hydrogen; a -CHO group.

    Amides

    • Functional derivatives of carboxylic acids where an amino group replaces the -OH of the carboxyl group.

    Amines

    • Organic compounds with one, two, or three hydrogens in ammonia replaced by carbon groups (RNH2, R2NH, or R3N).
    • Classified as primary (1º), secondary (2º), and tertiary (3º) based on the number of carbon groups bonded to the nitrogen atom.

    Amino Group

    • A nitrogen atom bonded to one, two, or three R groups (RNH2, R2NH, or R3N) where R represents a carbon group.

    Carbonyl Group

    • A C=O group.

    Carboxyl Group

    • A combination of carbonyl and hydroxyl groups: a -COOH group.

    Carboxylic Acids

    • Compounds containing a -COOH group.

    Carboxylic Esters

    • Derivatives of carboxylic acids where a carbon group replaces the H of the carboxyl group; -COOR or -CO₂R.

    Condensed Structural Formula

    • A shorthand method for writing organic structures grouping hydrogens with the atom they're attached to.

    Functional Group

    • The group of atoms that defines a compound's identity.
    • It causes predictable physical and chemical behaviors within a molecule.

    Hydroxyl Group

    • An -OH group bonded to a tetrahedral carbon atom.

    Ketones

    • Compounds containing a carbonyl group (C=O) bonded to two carbon groups.

    Organic Chemistry

    • The study of carbon compounds.
