Question

Graphite is a good conductor of electricity because it has

• A. delocalised protons.
• B. delocalised electrons.
• C. no electrons.
• D. localised electrons.

Answer 1

The correct option is B delocalised electrons.

Graphite is a good conductor of electricity because it has delocalised electrons. The structure of graphite is formed by every carbon covalently bonding itself to three other carbon atoms. The last electron in every carbon atom is not bonded with any other carbon atom and is free to move. Therefore graphite has the ability to conduct electricity.
