  • 1. Structural Isomers
    A structural isomer is a chemical formula that has more than one shape.
    "structural isomers." http://wwwchem.csustan.edu/chem3070/images/pentane.gif. Web. 1 Mar 2010.
  • 2. Saturated/Unsaturated Hydrocarbons
    Saturated hydrocarbons have single bonds and cannot bond with compounds anymore.
    Unsaturated hydrocarbons have double or triple bonds and can bond with compounds.
  • 3. Halogenated Hydrocarbons
    Are produced When a Hydrocarbon has one or more hydrogen group replaced with a Halogen(group 17)
    Can help create a saturated hydrocarbon by breaking double or triple bonds.

  • 4. Carboxylic Acids
    The Basic Structure is R-COOH (R can be replaced by a hydrogen)
    They are used in an esterfication reaction with an alcohol
    When naming you change the ending to “oic” acid (methane would be methanoic acid)
    They have hydrogen bonds increasing their boiling points.
  • 5. Structuralformulas
    The structural formula of a chemical compound is a graphical representation showing how the atoms are arranged.
    This is a structural formula where atoms are arranged forming a compound
    Structural formulas rock my world!!!

  • 6. Esterification
    http://en.wikipedia.org/wiki/Esterification
    This is an Esterification reaction
    I love Esterification reactions because they smell good
    Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and a carboxylic acid) form an ester as the reaction product.
  • 7. Addition Reaction
    An addition reaction is the reaction between two or more unsaturated hydrocarbons to produce one large molecule.
  • 8. Substitution Reaction
    When a carbon-hydrogen bond breaking occurs in an alkane or aromatic organic reaction
    An example is the reaction in which the chlorine atom in chloromethane is displaced by the hydroxide ion to form methanol
    CH3Cl + -OH      CH3OH + Cl-
  • 9. Addition and substitution reaction Video

  • 10. Combustion Reactions
    + H2O
    • Combustion reactions are the breakdown of hydrocarbon and oxygen to produce water and carbon dioxide.
    • 11. A Complete Combustion reaction is when the reactant will burn in oxygen producing a limited number of products.
    • 12. An incomplete combustion reaction is when there isn’t enough oxygen to react with.
    C?H? + O2 CO2 + H2O
    C?H? + O2 CO + H2O

  • 13. Monomers
    monomer - a simple compound whose molecules can join together to form polymers.
  • 14. Polymers
    Polymers are created when two or more monomers are linked together in a chain like pattern
  • 15. Polymerization
    Polymerization - The chemical process, normally needs the aid of a catalyst, to form a polymer by bonding together monomers.

  • 16. Polymers are made from Monomers
