In graphide electrons are

Options

(a) localised on each C-atom
(b) localised on every third C-atom
(c) spread out between the structure
(d) present in anti-bonding orbital.

Correct Answer:

localised on every third C-atom

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 π bond.A graphite consists of two layers which are separated by a distance of 340 pm.
