Introduction to Chemistry

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
Physical Chemistry

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

7
Biochemistry

• Biochemistry studies
• Organic compounds and the processes they go
  through.
• On the molecular level, they research
• Structure and Function
• Example
• Photosynthesis / Krebs Cycle

8
Analytical Chemistry

• Analytical Chemistry tells
• Chemical Composition
• Qualitative
• What we have
• Quantitative
• How much we have

9
Analytical Chemistry (cont.)

• Types
• IR Infrared Spectroscopy
• NMR Nuclear Magnetic Resonance
• Samples
• IR can be solid, liquid or gas
• NMR must be liquid

10
Theoretical Chemistry

• Theoretical Chemistry uses mathematics and
  computers to understand chemical behaviors and to
  predict the properties of new compounds

11
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
