    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

    • a compound containing a carbonyl group (C=O) bonded to a hydrogen; a -CHO group

    Amide

    • a functional derivative of a carboxylic acid in which an amino group replaces the -OH of the carboxyl group

    Amine

    • an organic compound in which one, two, or three hydrogens of ammonia are 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 of the amino group

    Amino Group

    • a nitrogen atom bonded to one, two, or three R groups, RNH2, R2NH, or R3N, where the symbol R represents a carbon group

    Carbonyl Group

    • a C=O group

    Carboxyl

    • carbonyl + hydroxyl group: a -COOH group

    Carboxylic Acid

    • a compound containing a -COOH group

    Carboxylic Ester

    • a derivate of a carboxylic acid in which a carbon group replaces the H of the carboxyl group; -COOR or -CO₂R

    Condensed Structural Formula

    • a shorthand method for writing organic structures in which hydrogens are grouped with the atom they are attached to

    Functional Group

    • the group of atoms that gives a compound its identity; group of atoms within a molecule that shows a characteristic set of predictable physical and chemical behaviors

    Hydroxyl (-OH) group

    • an -OH group bonded to a tetrahedral carbon atom

    Ketone

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

    Organic Chemistry

    • the study of carbon compounds
