Carbon its compounds
> The bonds formed by sharing of electrons are called covalent bonds.
> Formation of ions doesn't take place in sharing of electrons, thus these compounds don't conduct electricity.
> They have low melting and boiling points.
> The phenomenon due to which an element exhibits various physical properties is called allotropy.
> 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.
