Textbook Question

Identify the following compounds as primary, secondary, or tertiary amines. <IMAGE>

Verified step by step guidance

Identify the nitrogen atom in each compound, as it is the key atom in determining the type of amine.

Count the number of carbon-containing groups (alkyl or aryl groups) directly attached to the nitrogen atom.

Classify the amine based on the number of carbon-containing groups attached to the nitrogen: primary (1 group), secondary (2 groups), or tertiary (3 groups).

For each compound, note the structure and the number of carbon groups attached to the nitrogen to determine its classification.

Review the definitions: a primary amine has one carbon group attached, a secondary amine has two, and a tertiary amine has three.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Amines

Amines are organic compounds derived from ammonia (NH3) by replacing one or more hydrogen atoms with alkyl or aryl groups. They are classified based on the number of carbon-containing groups attached to the nitrogen atom: primary amines have one carbon group, secondary amines have two, and tertiary amines have three. Understanding the structure of amines is crucial for identifying their classification.

Primary, Secondary, and Tertiary Amines

The classification of amines is based on the number of carbon groups bonded to the nitrogen atom. A primary amine has one carbon group and two hydrogen atoms, a secondary amine has two carbon groups and one hydrogen atom, and a tertiary amine has three carbon groups and no hydrogen atoms. This classification affects the chemical properties and reactivity of the amines.

Structural Representation

To identify amines as primary, secondary, or tertiary, it is essential to analyze their structural formulas. Structural representation shows how atoms are arranged and connected, allowing for the determination of the number of carbon groups attached to the nitrogen. Recognizing these structures is key to accurately classifying the amines in question.
