NEET levelSingle correct optionDifficulty 1 of 3pb184

The hybridisation state of carbon atoms in graphite is

A $s p^{3} d$
B $s p$
C $s p^{3}$
D $s p^{2}$

Answer: D

Each carbon in graphite is bonded to three others in a planar hexagonal layer, using three

s p^{2}

orbitals. The fourth electron is in an unhybridised

p

orbital and is delocalised.
