  1. Introduction to Chemistry

  2. WHAT IS CHEMISTRY??? • By definition, Chemistry is the study of: Composition of Matter (What stuff is made up of) • AND • Changes that occur to that matter

  3. Chemistry became a science because people are naturally curious! Chemistry is very practical and has many applications to everyday life.

  4. Chemistry is broken into 6 major areas of study: • Organic Chemistry • Inorganic Chemistry • Biochemistry • Physical Chemistry • Analytical Chemistry • Theoretical Chemistry • Research

  5. There is overlap between these major areas of study so you can’t talk about one area of study without relating to another area.

  6. Organic Chemistry • Chemistry of compounds that contain the element "carbon" • Found in living systems • Used in artificially made products • Sucrose C6H12O6 • NaCl  X

  7. Inorganic Chemistry • Chemistry of compounds that DONOT contain “carbon” • BaCl2 • NaOH • CH4 • Fe2O3 X

  8. Analytical Chemistry • Chemistry that defines the chemical composition of a material • Qualitative = tells what it is • Quantitative = tells how much there is • Examples: • IR = Infrared Spectroscopy • NMR = Nuclear Magnetic Resonance

  9. Physical Chemistry • Chemistry that deals with physical properties of a material • Properties that can be measured • Generate data on the material • Examples: • Temperature • Freezing Point • Melting Point • Boiling Point • Density • Color

  10. Biochemistry • Chemistry of organic compounds • and • the processes they go through • Molecular level • Cell structure • Function • Processes • Photosynthesis • Krebs cycle • Genetics

  11. Theoretical Chemistry • Using mathematics and computers to understand principles behind observed chemical behavior and to predict properties of new compounds. • Quantum mechanics – explaining the probability of finding electrons within the electron cloud. • Composition of Jupiter

  12. Research is done for different reasons. The type of research pursued is dependent on what information is important / needed.

  13. Basic or Pure Research: The main goal of this type of research is to gain newknowledge about a chemical or process, just for the sake of knowledge. Chance discoveries can result from basic research. “I wonder what would happen if…”

  14. Applied Research: The main goal of this type of research is to solve a specificproblem. • Example: CFC’s (chlorofluoro carbons) • in refrigerants destroyed the ozone so chemists formulated new refrigerants.

  15. Technological Development: • This type of research involves the making and use of products that • improve the quality of life. • Development can result from Basic • Research. Examples: Teflon coating
