c. <IMAGE>

Verified step by step guidance

Identify the nitrogen atom in the amine structure.

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

If there is one carbon-containing group attached, classify the amine as primary (1°).

If there are two carbon-containing groups attached, classify the amine as secondary (2°).

If there are three carbon-containing groups attached, classify the amine as tertiary (3°).

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 determining their classification as primary, secondary, or tertiary.

Primary, Secondary, and Tertiary Amines

Primary amines (1°) have one alkyl group attached to the nitrogen, secondary amines (2°) have two, and tertiary amines (3°) have three. This classification affects the amine's chemical properties and reactivity. Recognizing the number of carbon groups is essential for accurate classification.

Structural Representation

The structural representation of amines, often depicted in molecular diagrams, shows the arrangement of atoms and bonds. This visual representation helps in identifying the type of amine by illustrating how many carbon groups are bonded to the nitrogen atom. Analyzing these structures is key to classifying the amines correctly.
