9th Grade Chapter 7 Lesson 2

  1. 1. 9 th Grade Chapter 7 Lesson 2 Pgs. 172-180 For Student Use Only
  2. 2. Organic Chemistry <ul><li>Life Chemistry </li></ul><ul><ul><li>Organic chemistry is the study of living chemistry </li></ul></ul><ul><ul><li>Inorganic Chemistry is the study of non-living chemistry </li></ul></ul><ul><ul><ul><li>Organic Chemistry deals with Carbon or carbon containing elements </li></ul></ul></ul>
  3. 3. Uniqueness of Carbon <ul><li>Why are we referred to as carbon-based life forms? </li></ul><ul><li>More elements are formed with carbon than any other elements </li></ul><ul><li>There are an estimated 5 million carbon compounds </li></ul>
  4. 4. Carbon Notes <ul><li>Carbon forms 4 covalent bonds </li></ul><ul><li>Carbon can bond to form several different shapes. </li></ul><ul><li>Carbon atoms may form single, double, or triple bonds </li></ul><ul><li>Carbon may form single or double bonds with atoms of many other elements </li></ul><ul><li>Carbon may form compounds that contain different structural arrangements and combinations with the same molecular formula (different shape, but same formula) </li></ul><ul><li>Notes from movie: “When Carbon Combines- Useful Carbon & Element of Life” </li></ul>
  5. 5. Hydrocarbons <ul><li>Movies Notes: Hydro-Carbons </li></ul><ul><li>Many organic compounds contain hydrogen and carbon </li></ul><ul><li>Hydrocarbons are combinations of hydrogen and carbon </li></ul><ul><li>Naming: </li></ul><ul><ul><li>Single bond= -ane </li></ul></ul><ul><ul><li>Double bond= -ene </li></ul></ul><ul><ul><li>Triple bond= -yne </li></ul></ul><ul><li>More naming rules: </li></ul><ul><ul><li>Prefix tells number of carbons in chain </li></ul></ul><ul><ul><li>See chart pg. 173 </li></ul></ul>
  6. 6. Hydrocarbons <ul><li>Hydrocarbons: </li></ul><ul><ul><li>Alkanes- single bonded carbons </li></ul></ul><ul><ul><li>Alkenes- have one or more double bonds </li></ul></ul><ul><ul><li>Alkynes- have one more triple bonds </li></ul></ul><ul><ul><li>Cyclic Hydrocarbons- found in a circle </li></ul></ul><ul><ul><li>Aromatic compounds- cyclic in shape but have pleasant smell (but can be posinous like benzene) </li></ul></ul><ul><li>Movie notes: Elements of Chemistry: The element of life </li></ul>
  7. 7. Substituted Hydrocarbons <ul><li>Elements of Life: Function Groups </li></ul><ul><li>Substituted Hydrocarbons: </li></ul><ul><ul><li>One or more hydrogens are replaced with something else. </li></ul></ul><ul><ul><li>Groups of atoms that replace the hydrogen is called a functional group </li></ul></ul><ul><li>Types of Hydrocarbons: </li></ul><ul><ul><li>Haloalkanes- hydrogen(s) is replaced with Halogen </li></ul></ul><ul><ul><li>Alcohols- hydrogen(s) is replaced with an –OH group </li></ul></ul><ul><ul><li>Carboxylic Acids- contains a COOH (carboxyl group), end in –oic </li></ul></ul><ul><ul><li>Esters- COO- replaces a hydrogen, end in -ate </li></ul></ul>
  8. 8. Other Hydrocarbons <ul><li>Soap: </li></ul><ul><ul><li>Has a long chain with polar and non-polar ends </li></ul></ul><ul><ul><li>Detergents- artificial soap that can work in “hard water” </li></ul></ul><ul><li>Polymers: </li></ul><ul><ul><li>Molecular chains (think slime lab) of monomers </li></ul></ul><ul><ul><li>Polymerization creates polymers (links monomers together) </li></ul></ul><ul><li>Common Polymers: </li></ul><ul><ul><li>Styrofoam (polystyrene) </li></ul></ul><ul><ul><li>PVC (polyvinylchloride) </li></ul></ul><ul><ul><li>Teflon (polytetrafluroethylene) </li></ul></ul><ul><ul><li>DNA (Deoxyribonucleic acid) </li></ul></ul><ul><li>Movie Notes: </li></ul>
