Work Step by Step

1. Find the parent chain and where we should start counting the carbons: The parent chain has to contain the amine group (NH2), and it has to be as large as possible, so the 2 carbons on the top will not be part of it. We should start counting from the carbon that has the amine group. 2. Functional group: - 1 Amine group on the carbon number 1: "amine" 3. Insaturations and number of carbons on the parent chain: - No insaturations: "an" - 5 carbons in the parent chain: "pent". 4. Substitutents: - 1 ethyl group on the carbon number 2: "2-ethyl" 5. Stereoisomerism: No stereoisomerism (No double bonds). 6. Put them all together: 2-ethylpentanamine.
