• Organic chemistry is the study of compounds of carbon.
• A functional group is an atom or group of atoms which is responsible for the
characteristic properties of a series of organic compounds.

,Hydrocarbons: Compounds that contain carbon and hydrogen only.
Saturated: Contain only single bonds.
Homologous Series: A series of compounds of uniform chemical type, showing
graduation in physical properties with a general formula for it’s members. They have a
similar method of preparation.

,Tetrahedral Carbon Compounds
Alkanes are tetrahedral carbon compounds. These are a homologous series, most of
these alkanes are fairly un reactive and are found naturally occuring. For example
Methane can be made in a biomass degenerator,
i.e. letting manure decay under anaerobic conditions. Methane however forms an
explosive mixture with air.
A hydrocarbon is a compound that contains hydrogen and carbon only. Many
hydrocarbons again, are naturally occuring and have been formed in the earth over
millions of years, e.g. crude oil, coal etc...
A homologous series is a series of compounds of uniform chemical type.
• Showing gradations in physical properties
• Having a general formula for all of its members
• Each member differs from the previous member by a CH2 unit.
Tetrahedral bond angles = 109 degrees
There are 3 types of tetrahedral carbon compounds on our course:
• Alkanes
• Alcohols
