Answer
(trans)-5-chloro-6-fluoro-5,6-dimethyloct-2-ene
Work Step by Step
1. Find the parent chain and where we should start counting the carbons:
- Since there are no bifurcations, the parent chain will have all carbons.
- We should start counting from the left, because the double bond is closer to this side.
2. Functional group:
- No functional group: "e".
3. Insaturations and number of carbons on the parent chain:
- 1 double bond on the carbons number 2 and 3: "2-en"
- 8 carbons in the parent chain: "oct".
4. Substitutents:
- 1 Chloro on the carbon number 5: "5-chloro"
- 2 Methyls on the carbons number 5 and 6: "5,6-dimethyl"
- 1 Fluoro on the carbon number 6: "6-fluoro"
**Dont forget to alphabetize it: "5-chloro-6-fluoro-5,6-dimethyl"
5. Stereoisomerism:
- 2 opposite hydrogens on the carbons with the double bond: "(trans)"
6. Put them all together:
(trans)-5-chloro-6-fluoro-5,6-dimethyloct-2-ene
