Carbon exists in several allotropic forms and can form single, double, or triple covalent bonds with other carbon atoms. It has a versatile nature due to its ability to catenate, or form straight or branched chains or rings of different sizes through covalent bonds. Carbon compounds are classified as saturated if they only contain single bonds, or unsaturated if they contain one or more double or triple bonds.

14. The phenomena of
existence of an element in two
or more forms which have
different physical properties
but chemical properties are
same that is called allotropy
and the different forms are
called allotropic forms.

19.  Saturated compounds:- Compounds of
carbon which have only single covalent bonds
between the carbon atoms are called
saturated compounds.
 Unsaturated compounds:- Compounds of
carbon which contain one or more double or
triple bonds between the carbon atoms is
called unsaturated compounds.
