1. Alkene Reactions
Addition Reactions - only one product
1. Hydrogenation (H2): Alkene + Hydrogen --> Alkane
2. Halogenation (X2): Alkene + diatomic halogen --> Dihaloalkane
3. Halgenation (HX): Alkene + HX --> Haloalkane
4. Hydration (HOH): Alkene + HOH --> alcohol
5. Polymerization: Many alkenes add together into a long alkane chain

3. 1. Hydrogenation Reaction
Alkene + Hydrogen --> Alkane
Hydrogen molecule adds to carbons with double bond.

5. Alkene Reactions

6. 2. Halogenation Reaction
Alkene + Halogen --> Dihaloalkane
Halogen molecule adds to carbons with double bond.

7. Alkene Reactions

8. Unsymmetrical Addition Reactions
Markovnikov’s Rule
For double bonds that have unequal numbers of hydrogen atoms attached.
For unsymmetrical reactants such as HX and HOH
The hydrogen of the reactant goes to the carbon of the double bond that already has the most hydrogen atoms. “the rich get richer”
The -X or the -OH go the other carbon (the one with the least amount of hydrogen

9. 3. Halogenation Reaction
Alkene + HX --> haloalkane
HCl molecule adds to carbons with double bond.

10. Alkene Reactions

11. 4. Hydration Reaction
Alkene + HOH --> alcohol
HOH molecule adds to carbons with double bond.

12. Alkene Reactions

13. 5. Polymerization Reaction
Alkene + Alkene + Alkene --> long chain of carbons
Double bonds convert to single bonds
