(a) Buckminster fullerene is an allotrope of carbon.

(b) Diamond is a good conductor of electricity.

(c) Graphite is a good conductor of electricity.

(d) Each carbon atom in graphite attached to other three carbon atoms.

Answer 1

(b) Diamond is a good conductor of electricity.

Allotropes of carbon: Carbon allotropes refer to different well-defined structures of carbon-pure materials, in which carbon atoms are bonded in specific ways. Carbon shows allotropic forms like Diamond, graphite, and Buckminsterfullerene.
