Organic chemistry is the branch of chemistry devoted to the study
of compounds of carbons.
However, the oxides of carbon (CO, CO2),
carbonates

(CO3 ) bicarbonates (HCO3) and cyanides (CN)
etc. are exceptions to this general definition. These carbon containing
compounds do not contain a functional group in their molecules. These are studied
under inorganic chemistry.
Hydrocarbons are organic compounds in which carbon atoms are
joined to H-atoms by covalent bonds. All other compounds could be regarded as
derivatives of hydrocarbons. Thus another definition of organic chemistry could
be:
"a study of hydrocarbons and their derivatives"
This appears to be a
more appropriate definition as the study of oxides of carbon, carbonates or
bicarbonates is kept out of its preview.
