What is the primary reason graphite is a good conductor of electricity while diamond is not?
AGraphite has a lower density
BGraphite has delocalized pi electrons
CDiamond is too hard for electrons to move
DGraphite contains metal impurities
✓ Correct Answer: B — Graphite has delocalized pi electrons
In graphite's sp2 hybridization, one valence electron per carbon remains in a p-orbital and is free to move throughout the layer.
