In diamond each carbon is bonded with four other carbon atoms. So hybridisation of carbon atom is

s p^{3}

.
In graphite each carbon is bonded with three other carbon atoms. So hybridisation of carbon atom is

s p^{2}

.

Q. Choose the correct statement:

Both diamond and graphite are used as dry lubricants.

Diamond and graphite have two dimensional network.

Diamond is covalent and graphite is ionic.

Diamond is $s p^{3}$ hybridised and graphite is $s p^{2}$ hybridized.

In diamond each carbon is bonded with four other carbon atoms. So hybridisation of carbon atom is $s p^{3}$ .
In graphite each carbon is bonded with three other carbon atoms. So hybridisation of carbon atom is $s p^{2}$ .
