1. Drill: Draw & name 2 isomers of C4H10

2. Alkenes

3. Hydrocarbons with at least one double bond
Alkenes
Hydrocarbons with at least one double bond

4. Alkenes
Each double bond reduces the number of hydrogens in the hydrocarbon by two

5. All alkenes are unsaturated hydrocarbons

6. Unsaturated Hydrocarbons
Contain less than the maximum number of hydrogens

7. Alkenes

8. Naming Alkenes
Number the carbons on the chain; so that, the double bond has the lowest possible number

9. Naming Alkenes
The double bond will always fall between two numbered carbons

10. Naming Alkenes
Apply the lower of those two numbers to the double bond

11. Naming Alkenes 4 2 1 3
2-butene

12. Problems 4 2 1 3 2 3 4 1

13. Geometric Isom. 4 2 1 3 2 3 4 1

14. Geometric Isomers
Isomers whose arrangement is same side (cis) or opposite side (trans) of a stationary bond

15. Naming Alkenes
Draw a line through the double bond parallel to each of the bonds in the double bond

16. Naming Alkenes 4 2 1 3

17. Naming Alkenes
If the two ends of the chain are on the same side of the line, it is a cis-double bond

18. Naming Alkenes
If the two ends of the chain are on opposite sides of the line, it is a trans-double bond

19. Naming Alkenes
Place cis or trans at the start of the name in the organic compound

20. Naming Alkenes 4 2 1 3
trans-2-butene

21. trans-3-ethyl-4,6-dimethyl-5-cyclopentyl-2-octene
