Introduction to Chemistry The Six Main Branches of Chemistry

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

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

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

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

Research Chemistry 1. Basic or Pure Research – to gain new knowledge 2. Applied Research – to solve a specific problem 3. Technological Development – used to improve the quality of life

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

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

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

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