Question

Name an allotrope of carbon that is a good conductor of electricity.​

Answer 1

Explanation:

Structure of graphite accounts for it being a good conductor of electricity. In its structure each carbon atom is directly attached to three carbon atoms through covalent bonds.

Answer 2

Answer:

Diamond is the hardest mineral known (10 on the Mohs scale), but graphite is one of the softest (1–2 on Mohs scale). Diamond is the ultimate abrasive, but graphite is soft and is a very good lubricant. Diamond is an excellent electrical insulator, but graphene is an excellent conductor.
