Statement A : Graphite conducts electricity. Statement B : Delocalisation of electrons occurs in graphite.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
In graphite, each carbon atom in hexagonal ring undergoes \({\text{s}}{{\text{p}}^{\text{2}}}\) -hybridisation and makes three sigma bonds with three neighbouring carbon atoms. Due to delocalisation of this fourth electron, graphite conducts electricity.

Assertion : Diamond and graphite do not have the same crystal structure. Reason : Diamond is crystalline while graphite is amorphous.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Diamond is polymeric giant \(3 \mathrm{D}\) molecule where has graphite as two dimensional layer like structure with hexagonal rings. Diamond and graphite both are crystalline forms of carbon. So, option (3) is correct.
