Branches of Chemisty

Intro To Chemistry:At the conclusion of our time

together, you should be able to:

1. List the 6 branches of chemistry and be able to give an example of each

2. List the 3 types of research in chemistry

Branches of Chemistry

• Many major areas of study for Many major areas of study for specializationspecialization

• Several career opportunitiesSeveral career opportunities

• Also used in many other jobsAlso used in many other jobs

Euphemisms in Science We all know that some politicians and government

spokesmen use certain euphemistic phrases to give an aura of respectability to descriptions of events or

actions which would be offensive when expressed in plain English. The following is a list of Euphemisms in

Science and their translations into plain English.

“Accidentally stained during mounting...”

Accidentally dropped on the floor!

#1 Branch of Chemistry

• Organic Chemistry – It is the scientific study of chemical compounds of carbon and hydrogen.

1. Organic Chemistry

• Organic chemists study the Organic chemists study the structure, function, structure, function, synthesis, and identity of synthesis, and identity of carbon compoundscarbon compounds

• Useful in petroleum Useful in petroleum industry, pharmaceuticals, industry, pharmaceuticals, polymerspolymers

#2 Branch of Chemistry

• Inorganic Chemistry – deals with molecules which do not contain carbon.

2. Inorganic Chemistry

• Inorganic chemists Inorganic chemists study the structure, study the structure, function, synthesis, function, synthesis, and identity of non-and identity of non-carbon compoundscarbon compounds

• Polymers, Polymers, MetallurgyMetallurgy

#3 Branch of Chemistry

Physical Chemistry – • Study of the physical properties of

chemical substances . • Typically studies changes in

temperature, pressure, volume, heat, and work of systems in the solid, liquid, and or gas phase.

3. Physical Chemistry

• Physical chemistry Physical chemistry is the physics of is the physics of chemistry… the chemistry… the forces of matterforces of matter

• Much of p-chem is Much of p-chem is computationalcomputational

• Develop theoretical Develop theoretical ideas for new ideas for new compoundscompounds

HONK if you passed p-chem

#4 Branch of Chemistry

• Analytical Chemistry – the identification and analysis of material samples to gain an understanding of their chemical composition, structure and function.

4. Analytical Chemistry

• Analytical Analytical chemistry is the chemistry is the study of high study of high precision precision measurementmeasurement

• Find composition Find composition and identity of and identity of chemicalschemicals

• Forensics, quality Forensics, quality control, medical control, medical teststests

IR (Infrared) Spectroscopy

1. Proton Nuclear Magnetic Resonance (1H NMR) Spectroscopy

2. Carbon-13 Nuclear Magnetic Resonance (13C NMR) Spectroscopy

Nuclear Magnetic Resonance

#5 Branch of Chemistry

Biochemistry – • The study of the chemical substances and

vital processes occurring in living organisms • Areas of biochemistry include cell

metabolism, the endocrine system, the genetic code (DNA, RNA), protein synthesis, cell membrane transport, and signal transduction.

5. Biochemistry

• Cross between Cross between biology and biology and chemistrychemistry

• Pharmaceuticals Pharmaceuticals and geneticsand genetics

#6 Branch of Chemistry

• Theoretical Chemistry – the prediction of the properties of new compounds without using traditional laboratory equipment.

For Example:Ununseptium• Atomic Number: 117• Atomic Weight: Approximately 294 amu• Melting Point: Higher than Astatine• Boiling Point: Higher than Astatine• Density: Higher than Astatine• Phase at Room Temperature: Expected to be

a Solid• Element Classification: Non-metal• Should be Radioactive, Not Yet Produced• Period Number: 7• Group Number: 17• Group Name: Halogen• What's in a name? Will hold a temporary

name that means one-one-seven.

3 Types of Research

• Basic/pure – gain new knowledge; simple curiosity.

• Applied – to meet the goals defined by a specific problem.

• Technological – to improve human life.
