  1. Introduction to Chemistry The Six Main Branches of Chemistry

  2. What is Chemistry??? • Chemistry is the study of the composition of matter. (what stuff is made of) • Changes that occur to that matter.

  3. Organic Chemistry What one element off of the periodic table does a compound have to have to be “organic”? Carbon

  4. Organic Chemistry (cont.) When structures have the same number of Carbons, but are structurally put together differently, they are called… Isomers

  5. Inorganic Chemistry Inorganic Chemistry is the study of compounds that do not contain Carbon How do you determine if a compound contains Carbon? Look for “C” in the formula

  6. Research Chemistry • Basic or Pure Research – to gain new knowledge • Applied Research – to solve a specific problem • Technological Development – used to improve the quality of life

  7. Physical Chemistry Physical Chemistry deals with properties that can be measured. Examples: Boiling Point Melting Point Density

  8. Biochemistry Biochemistry studies Organic compounds and the processes they go through. On the molecular level, they research Structure and Function Example: Photosynthesis / Kreb’s Cycle

  9. Analytical Chemistry Analytical Chemistry tells Chemical Composition Qualitative = “What” we have Quantitative = “How much” we have

  10. Analytical Chemistry (cont.) Types: IR = Infrared Spectroscopy NMR = Nuclear Magnetic Resonance Samples: IR = can be solid, liquid or gas NMR = must be liquid
