Which allotrope of carbon is a good conductor of electricity due to the presence of free electrons?
A. Diamond
B. Fullerene
C. Graphite✓ Correct Answer
D. Lampblack
💡 Solution & Explanation
Graphite conducts electricity well because each carbon atom is bonded to three others, leaving one delocalized electron free to move across the layered lattice. Diamond lacks free electrons due to its rigid tetrahedral sp3 covalent network, making it an electrical insulator. Fullerene molecules show semiconductor properties under specific conditions.
