Carbon And its Compounds

Carbon is a typical non-metal present in earth's crust to the extent of 0,02% by mass.

All living organisms contain carbon and hydrogen as their essential compounds.

The compounds of carbon are covalent in nature formed by the electron sharing in the bonding atoms.

Organic compounds are the hydrocarbons and their derivatives.

Allotropes of carbon

The three allotropes of carbon are:

Diamond

Graphite

Fullerene

Among these diamond is the hardest substance known

Graphite is a good conductor of heat and electricity

Uses of graphite

Graphite is used to make electrodes of electrolytic cells.

Being soft and greasy it is used to lubricate the parts of machines

It is also used as a moderator in nuclear power plants

Mixed with wax and clay, graphite is used for making cores of lead pencils as it can mark the paper black.
