  1. ALKANE REACTIONS

  2. REACTION MECHANISM

  3. REACTION MECHANISM • Is a step by step description of how a chemical reaction occurs.

  4. SUBSTITUTION REACTION

  5. SUBSTITUTIONREACTION • Is a chemical reaction in which an atom or group on a molecule is replaced by another atom or group. NOTE: replacement by a halogen is called HALOGENATION reaction …..

  6. EXAMPLE GENERAL FORMULA Alkane + Halogen -----------→ Haloalkane + Hydrogen Halides light heat H │ H – C – Cl │ H H │ H – C – H │ H Cl – Cl light Cl2 --------→ + H – Cl + heat HYDROGEN CHLORIDE chloromethane METHANE methylchloride

  7. iNDUSTRIAL APPLICATIONS

  8. COMBUSTION REACTION

  9. COMBUSTIONREACTION • Is a chemical reaction wherein hydrocarbon reacts with oxygen and produces Carbon Dioxide and water. NOTE: great amount of heat is released in this reaction…..

  10. EXAMPLE GENERAL FORMULA Hydrocarbon (Alkane) + Oxygen -----------→ Carbon Dioxide + Water CH4 + O2 2 2 --------→ CO2 H2O + METHANE 2 C2H6 O2 + --------→ + 7 4 CO2 6 H2O ETHANE

  11. iNDUSTRIAL APPLICATIONS
