Explain the difference in properties of diamond and graphite on the basis of their structures.
|It has a crystalline lattice.||It has a layered structure.|
|In diamond, each carbon atom is hybridized and is bonded to four other carbon atoms through a bond.||In graphite, each carbon is hybridized and is bonded to three other carbon atoms through a bond. The fourth electron forms a n bond.|
|It is made up of tetrahedral units.||It has a planar geometry.|
The C-C bond length in diamond is 154 pm.
|The C-C bond length in graphite is 141.5 pm.|
|It has a rigid covalent bond network which is difficult to break.||It is quite soft and its layers can be separated easily.|
|It acts as an electrical Insulator.||It is a good conductor of electricity.|
