I. Organic CompoundsI. Organic Compounds
Organic compounds Organic compounds = = are compounds that contain Carbon.(Some exceptions)
Organic means living things.
Many Organic compounds have similar properties such as boiling and melting point as well as odor and solubility.

IsomersIsomers are carbon compounds are carbon compounds with the same chemical formula with the same chemical formula but different structural formulas.but different structural formulas.
There can be so many different There can be so many different isomers of carbon because carbon isomers of carbon because carbon can form can form single, double single, double and and triple triple bonds.bonds.

Organic compounds are formed mostly Organic compounds are formed mostly from the elements from the elements carbon, and carbon, and hydrogenhydrogen
but can also include elements like but can also include elements like oxygen, nitrogenoxygen, nitrogen , phosphorus, , phosphorus, sulfur, and otherssulfur, and others
HydrocarbonsHydrocarbons are organic compounds are organic compounds formed from only hydrogen and formed from only hydrogen and carboncarbon
