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