Question

Graphite is a good conductor of electricity. It is because of its

1. A. linear structure
2. B. tetrahedral structure
3. C. trigonal planar structure
4. D. hexagonal multilayer structure (Correct answer)

Correct Answer

Option D — hexagonal multilayer structure

Detailed Solution & Explanation

The correct answer is hexagonal multilayer structure.

Key Points

• Graphite conducts electricity due to its hexagonal multilayer structure.
• In each layer, carbon atoms form hexagonal rings with three covalent bonds — the fourth electron from each carbon is delocalized and free to move, allowing electrical conduction.
• This is unlike diamond, where all four electrons are covalently bonded, making it a non-conductor.
