An example of two molecules that contain carbon is compound methane ( 1 carbon bounded to four hydrogen. ) and Ethane ( two carbon atoms and four hydrogen ). Carbon is able to form so many molecules/compounds because each carbon atom can form four chemical bonds to other atoms and, because of its size, it fits in nicely as part of large molecules. Hope this helps!
The catenation can be defined as the the property of the carbon atom to bind to another atoms and form compounds. The carbon can combine with hydrogen to form hydrocarbon. This property helps in the formation of multiple number of carbon compounds.
Carbon can form single, double or triple bond based on the atom to which it is combining.
