Common mistake
Misclassification of Amines
Students often confuse primary, secondary, and tertiary amines, incorrectly classifying them based on the number of nitrogen atoms instead of the number of carbon atoms attached to the nitrogen.
Remember that primary amines have one carbon atom attached to the nitrogen, secondary amines have two, and tertiary amines have three. Focus on the carbon count to classify correctly.
