Verified step by step guidance1
Examine the structure of each compound in the image and identify the nitrogen atom (N) in the amine group. Amines are organic compounds that contain a nitrogen atom bonded to one or more alkyl or aryl groups.
Determine the number of carbon-containing groups (alkyl or aryl groups) directly attached to the nitrogen atom. This will help classify the amine as primary, secondary, or tertiary.
Recall the definitions: A primary amine has one carbon-containing group attached to the nitrogen atom, a secondary amine has two, and a tertiary amine has three.
For each compound, count the number of carbon-containing groups attached to the nitrogen atom and classify it accordingly. For example, if the nitrogen is bonded to one carbon group and two hydrogens, it is a primary amine.
Repeat the process for all compounds in the image, ensuring you carefully analyze the bonding around the nitrogen atom to avoid misclassification.

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. Understanding the structure of amines is crucial for identifying their classification as primary, secondary, or tertiary.

Amine Classification Example 1
Primary, Secondary, and Tertiary Amines
Primary amines have one alkyl or aryl group attached to the nitrogen atom, secondary amines have two, and tertiary amines have three. This classification affects their chemical properties and reactivity. Recognizing the number of substituents on the nitrogen is essential for correctly identifying the type of amine.

Structural Representation
Structural representation of compounds, such as Lewis structures or condensed formulas, visually depicts the arrangement of atoms and bonds. This representation is vital for analyzing the molecular structure of amines, allowing one to determine the classification based on the connectivity of the nitrogen atom to carbon groups.
