Organic Chemistry Functional Groups Quiz

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 attached 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 where an amino group replaces 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) based on the number of carbon groups attached 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 R represents a carbon group.

Carbonyl Group

• A C=O group.

Carboxyl Group

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

Carboxylic Acid

• A compound containing a -COOH group.

Carboxylic Ester

• A derivative of a carboxylic acid 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; a group of atoms within a molecule that exhibits predictable physical and chemical behaviors.

Hydroxyl Group (-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.
