The hybridisation of each carbon atom in graphite is

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

Answer: D

Each carbon in a graphite layer is bonded to three other carbons by sigma bonds in a plane. Three sigma bonds mean

s p^{2}

hybridisation, and the fourth electron sits in an unhybridised

p

orbital that forms the delocalised

π

cloud.
