COMPOUNDS OF CARBON. Conceptual Chemistry Chapter 12. CARBON !!!!. Carbon atoms have the ability to link together and form molecules made up of many carbons atoms. Add to this, the fact that any of the carbon atoms can also bond with atoms of other elements, and you see

Life is based on carbon’s ability to bond with other carbon atoms to form diverse structures. The branch of chemistry that is the study of carbon-containing compounds has come to known as ORGANIC CHEMISTRY
The hydrocarbon OCTANE has eight carbons per molecule and is a component of gasoline.
The hydrocarbon POLYETHYLENE contains hundreds of carbon and hydrogen atoms per molecule and is the plastic used to make many items, such as milk containers and plastic bags.
In all of the hydrocarbons that were discussed so far, each carbon atom is bonded to four neighboring atoms by four single covalent bonds. Such hydrocarbons are known as
A hydrocarbon in which each carbon atom is bonded to at least four other atoms.
A hydrocarbon in which a carbon atom is bonded to less than four other atoms.
(This occurs when the hydrocarbon has a double or triple bond)
Also known as
Polypeptides are polymeric biomolecules that are made up of ten or more amino acids.
In addition to those naturally occurring polymers, there are even more synthetic, or man-made, polymers. What were some examples of the polymers that we have already discussed?
With all of this talk about carbon and its unique bonding properties, it is important to note that the same carbon atoms are used repeatedly over and over on Earth. These atoms cycle between the Earth and the atmosphere.
Plants use carbon to make food
Decomposers break down dead things, releasing carbon to atmosphere and
Plants and animals die
Fossil fuels are burned; carbon is returned to atmosphere
Animals eat plants and take in carbon
Bodies not decomposed — after many years, become part of oil or coal deposits
Carbon slowly released from these substances returns to atmosphereCarbon Cycle Diagram
