Currently over twentymillion compounds have been reported in thechemical literature; about 90% of them areorganic, ie they contain carbon. The remainingcompounds are called inorganic and are formedfrom the other elements, of which there areabout 100. That carbon so dominatescompound formation is a result of the fact that itis almost unique in its ability to form longchains with other carbon atoms. [Carbon sneighbor in the periodic table, silicon, can dothis but rarely does.] These chains with onecarbon joined to a second and the secondjoined to a third, etc., can be branched, ie,chains of carbon atoms can be attached tocarbons in the original chain.
Experiment #3 Hydrocarbons Page 2 Hydrocarbons may be saturated or unsaturated.A saturated hydrocarbon is one that is maxed out in terms of the number of hydrogens that can be present given the number of carbons in the compound; it is impossible to add more hydrogen atoms to the compound so it is saturated with hydrogen.
