Key Concepts Unit A Chemistry 30

  1. 1. Structural Isomers<br />A structural isomer is a chemical formula that has more than one shape.<br />"structural isomers." http://wwwchem.csustan.edu/chem3070/images/pentane.gif. Web. 1 Mar 2010. <br />
  2. 2. Saturated/Unsaturated Hydrocarbons<br />Saturated hydrocarbons have single bonds and cannot bond with compounds anymore.<br />Unsaturated hydrocarbons have double or triple bonds and can bond with compounds.<br />
  3. 3. Halogenated Hydrocarbons<br />Are produced When a Hydrocarbon has one or more hydrogen group replaced with a Halogen(group 17)<br />Can help create a saturated hydrocarbon by breaking double or triple bonds.<br />http://www.youtube.com/watch?v=1qGPWdm2MlI (watch to 1:50)<br />
  4. 4. Carboxylic Acids<br />The Basic Structure is R-COOH (R can be replaced by a hydrogen)<br />They are used in an esterfication reaction with an alcohol<br />When naming you change the ending to “oic” acid (methane would be methanoic acid)<br />They have hydrogen bonds increasing their boiling points.<br />
  5. 5. Structuralformulas<br />The structural formula of a chemical compound is a graphical representation showing how the atoms are arranged.<br />This is a structural formula where atoms are arranged forming a compound<br />Structural formulas rock my world!!!<br />http://en.wikipedia.org/wiki/Structural_formula<br />http://www.1-formula.com/upl/Image/800px-Acetone-structural.png<br />
  6. 6. Esterification<br />http://en.wikipedia.org/wiki/Esterification<br />This is an Esterification reaction<br />I love Esterification reactions because they smell good<br />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.<br />
  7. 7. Addition Reaction<br />An addition reaction is the reaction between two or more unsaturated hydrocarbons to produce one large molecule.<br />
  8. 8. Substitution Reaction<br />When a carbon-hydrogen bond breaking occurs in an alkane or aromatic organic reaction<br />An example is the reaction in which the chlorine atom in chloromethane is displaced by the hydroxide ion to form methanol <br />CH3Cl + -OH      CH3OH + Cl-<br />
  9. 9. Addition and substitution reaction Video<br />http://www.youtube.com/watch?v=nVDUB4mWJ8M<br />
  10. 10. Combustion Reactions<br />+ H2O<br /><ul><li>Combustion reactions are the breakdown of hydrocarbon and oxygen to produce water and carbon dioxide.
  11. 11. A Complete Combustion reaction is when the reactant will burn in oxygen producing a limited number of products.
  12. 12. An incomplete combustion reaction is when there isn’t enough oxygen to react with.</li></ul>C?H? + O2 CO2 + H2O<br />C?H? + O2 CO + H2O<br />"combustion reactions.". http://upload.wikimedia.org/wikipedia/commons/3/3c/Et_baal.jpg. Web. 1 Mar 2010<br />
  13. 13. Monomers <br />monomer - a simple compound whose molecules can join together to form polymers. <br />
  14. 14. Polymers<br />Polymers are created when two or more monomers are linked together in a chain like pattern<br />
  15. 15. Polymerization<br />Polymerization - The chemical process, normally needs the aid of a catalyst, to form a polymer by bonding together monomers. <br /> http://www.youtube.com/watch?v=LJ5hjUeZt7U&feature=related<br />
  16. 16. Polymers are made from Monomers <br />http://www.youtube.com/watch?v=Jpv2RUjNFjo<br />
