(b) Graphite. Is also an allotrope of carbon. In graphite, each carbon atom is bonded to three other carbon atoms by strong covalent bonds. Since each carbon atom is bonded to only three others, only three of the four valence electrons in each carbon are used in bonding hence presence delocalized electrons in the structure of graphite.
