    Study Notes

    Alcohol

    • A compound containing 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.

    Aldehyde

    • Contains a carbonyl group (C=O) bonded to a hydrogen atom, forming a -CHO group.

    Amide

    • A functional derivative of a carboxylic acid, with an amino group replacing the -OH of the carboxyl group.

    Amine

    • An organic compound with one, two, or three hydrogens of ammonia replaced by carbon groups (RNH2, R2NH, or R3N).
    • Classified as primary (1º), secondary (2º), and tertiary (3º), depending 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

    • A combination of a carbonyl and hydroxyl group, forming a -COOH group.

    Carboxylic Acid

    • Contains a -COOH group.

    Carboxylic Ester

    • A derivative of a carboxylic acid where a carbon group replaces the hydrogen of the carboxyl group, represented as -COOR or -CO₂R.

    Condensed Structural Formula

    • A shorthand representation of organic structures where hydrogens are grouped with the atom they're attached to.

    Functional Group

    • A group of atoms within a molecule that defines its chemical behavior and properties.

    Hydroxyl (-OH) group

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

    Ketone

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

    Organic Chemistry

    • The study of carbon compounds.
