Introduction to Chemistry

The Six Main Branches of Chemistry


What is chemistry l.jpg
What is Chemistry???

  • Chemistry is the study of the composition of matter.

    (what stuff is made of)

  • Changes that occur to that matter.


Organic chemistry l.jpg
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 l.jpg
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 l.jpg
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


Physical chemistry l.jpg
Physical Chemistry

Physical Chemistry deals

with properties that can be measured.

Examples:

Boiling Point

Melting Point

Density


Biochemistry l.jpg
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 l.jpg
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
