Answer

(trans)-oct-2-en-4-ol.

Work Step by Step

1. Find the parent chain and where we should start counting the carbons: - Since there are no bifurcations of carbons, the parent chain will have all the carbons in the molecule and the functional group (-OH). - We should start counting from the right, because the alcohol group (-OH) is closer to this side. 2. Functional group: - 1 Alcohol on the carbon number 4: "4-ol" 3. Insaturations and number of carbons on the parent chain: - 1 double bond on the carbons 2 and 3: "2-en" - 8 carbons in the parent chain: "oct" 4. Substitutents: - No substitutents. 5. Stereoisomerism: - 1 double bond, with 2 opposite hydrogens: "(trans)" 6. Put them all together: (trans)-oct-2-en-4-ol
