| Assertion: Graphite is a good conductor of electricity, however diamond belongs to the cateogry of insulators. |
| Reason: Graphite is soft in nature while diamond is very hard and brittle. |
A) Assertion and reason both are correct statements and reason is correct explanation for assertion.
B) Assertion and reason both are correct statements but reason is not correct explanation for assertion.
C) Assertion is correct statement but reason is wrong statement.
D) Assertion is wrong statement but reason is correct statement.
Correct Answer: B
Solution :
Reason is not the correct explanation for assertion. The correct reason is In graphite, carbon atoms are \[s{{p}^{2}}\] hybridised and have one free electron. In diamond, these are \[s{{p}^{3}}\] hybridised and there are no free electrons available for electrical conductivity.
