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


Diamond



Graphite



It has a crystalline lattice



It has a layered lattice



It acts as an electrical insulator.



It is a good conductor of electricity.



It is made up of tetrahedral units.



It has a planar geometry.



The C-C bond length in diamond is 154pm.



The C-C bond length is 141.5pm.



It has a rigid covalent bond network which is difficult to break.



It is quite soft and its layers can be separated easily.



Each carbon is sp3 hybridized.



Each carbon is sp2 hybridized.
