- 2> Catenation is the ability of an element to combine with itself through covalent bonds to form long chains. > The compounds of carbon having only single bonds between the atoms are called saturated compounds. Formula: Alkane; CnH2n+2. > The compounds of carbon having double and triple bonds between the atoms is called an unsaturated compound. Formula: Alkene; CnH2n. Alkyne; CnH2n-2.
