Question

Which of the following statements about graphite is correct?

• A. Graphite is a good conductor of electricity due to its free electrons.
• B. Graphite is a poor conductor of electricity because it lacks free electrons.
• C. Graphite does not conduct electricity as it is an insulator.
• D. Graphite conducts electricity only when heated above 100°C.

Hint:

Remember that the ability of graphite to conduct electricity is attributed to its free electrons resulting from its unique bonding structure.

Answer 1

The Correct Option is A

Graphite is an allotrope of carbon where each carbon atom is bonded to three others in a hexagonal lattice, leaving one free electron per atom. These free electrons allow graphite to conduct electricity, making option (A) correct. The other options are incorrect because they contradict the known electrical properties of graphite.
