Assertion: Among the carbon allotropes, diamond is an insulator, whereas, graphite is a good conductor of electricity.
Reason: Hybridization of carbon in diamond and graphite are and respectively.
Reason: Hybridization of carbon in diamond and graphite are and respectively.
Options
- ABoth assertion and reason are correct, but the reason is not the correct explanation for the assertion.
- BBoth assertion and reason are correct, but the reason is the correct explanation for the assertion.
- CBoth assertion and reason are incorrect.
- DAssertion is incorrect statement, but the reason is correct.
Correct answer
A. Both assertion and reason are correct, but the reason is not the correct explanation for the assertion.
Step-by-step solution
Diamond has strong Dimensional network structure as every carbon is linked with other carbons tetrahedrally via hybridization. In graphite, every carbon is linked to other carbon to forms sheet-like hexagonal structure, and the free electron is along with the layer so good conductor of electricity along with the layer.
