Carbon ChemistryForms of Pure Carbon
Diamonds: a crystal form of carbon
Carbon ChemistryForms of Pure Carbon
Graphite: layers of carbon bonded together

Other Structure: tubes, balls, cylinders etc.
Nanotube-used to make electrical circuits Fullerene-used to carry
drugs throughout the body
Carbon ChemistryCarbon Compounds
Any substance where the CARBON atom is the main atom is called an organic compound.
Many organic compounds have similar properties like LOW boiling points, LOW melting points, odor, no electrical conductivity, etc.
Most organic compounds are liquids or gasses at room temperature.
Carbon ChemistryThe most important of all organic molecules are called POLYMERS
Polymers are long chains of molecules made of smaller units called monomers.
Example: DNA, protein, starch and wood (cellulose)
Carbon ChemistryTypes of Carbon Compounds
HYDROCARBONS: compounds made of HYDROGEN AND CARBON
a.) very flammable
b.) formed from straight chains, branched chains and rings
c.) molecules are represented by a structural formulas
Carbon ChemistryISOMERS
Carbon compounds with the same chemical formula but with a different structural formulas
Carbon ChemistryISOMERS
Carbon compounds with the same chemical formula but with a different structural formulas
Carbon ChemistrySUBSTITUTED HYDROCARBONS:
any carbon compound where some of the hydrogen atoms have been replaced by other elements or groups.

Carbon ChemistryTypes of Substituted Hydrocarbons
Alcohols: when an –OH group is attached to a carbon chain
Organic Acids: when a –COOH group is attached to a carbon chain (vinegar is an organic acid)
Esters: often are carbon rings attached to a carbon chain which give the molecules a smell
Carbon ChemistrySmall molecules in the body include things like water, sugar, salts, amino acids, nucleic acids
H2O C6H12O6 NaCl
DNA is made of 4 bases: Adenine, Guanine, Cytosine and Thymine A-T C-G
