Question

Explain the difference in properties of diamond and graphite on the basis of their structures.

Answer 1

The difference in the properties of diamond and graphite are:

DIAMOND	GRAPHITE
Diamonds have a strong three-dimensional network structure	Graphites have a two-dimensional sheet-like structure
The networks are formed because of the presence of covalent bonds.	They are formed due to weak Van der Waal's forces of attraction.
They are hard in nature.	They are soft in nature.
Molecules are closely packed, as a result, they have high density.	There is a large gap between molecules. Therefore, they have low density.
There is no presence of free carbon atoms in diamonds.	There is presence of free Carbon atoms in graphite.
Diamonds do not conduct electricity.	Graphite conducts electricity.

Therefore, Diamond and Graphite are the allotropes of carbon, even though these minerals chemically consist of carbon atoms they have different physical properties.
