Title: Alkene%20Reactions


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

1. Hydrogenation Reaction
  • Alkene Hydrogen --gt Alkane
  • Hydrogen molecule adds to carbons with double
    bond.

2. Halogenation Reaction
  • Alkene Halogen --gt Dihaloalkane
  • Halogen molecule adds to carbons with double bond.

Unsymmetrical Addition Reactions
  • Markovnikovs 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

3. Halogenation Reaction
  • Alkene HX --gt haloalkane
  • HCl molecule adds to carbons with double bond.

4. Hydration Reaction
  • Alkene HOH --gt alcohol
  • HOH molecule adds to carbons with double bond.

5. Polymerization Reaction
  • Alkene Alkene Alkene --gt long chain of
    carbons
  • Double bonds convert to single bonds
