In graphite, electrons are:

1. Localised on every third C-atom
2. Present in anti-bonding orbital
3. Localised on each C-atom
4. Spread out over the structure

Correct answer: Spread out over the structure

Solution

In graphite, the carbon atoms are arranged in layers, and each carbon atom is sp2 hybridized. The unhybridized p-orbitals overlap to form a delocalized π-electron system, allowing electrons to be spread out over the entire structure.
