In graphite, electrons are
A.localised on each C-atom
B.localised on every third C-atom
C.spread out between the structure✓ Correct
D.present in antibonding orbital.
Explanation
In graphite each carbon atom undergoes sp2-hybridisation and is covalently bonded to three other carbon atoms by single bonds. The fourth electron forms -bond. The electrons are delocalised over the whole sheet i.e. electrons are spread out between the structure.
