Expert Answer:

 Diamond has a network structure consisting of a very large number of carbon atoms bonded to each other.
 Each carbon atom is sp³ hybridised and is bonded to four other carbon atoms by single covalent bonds.
 There is a three-dimensional network of strong covalent bonds in diamond which is very difficult to break.
 In graphite, each carbon atom undergoes sp² hybridisation and is covalently bonded to three other carbon atoms by single bonds.
 The fourth electron on each carbon atom forms  bonds.
 In this way, graphite consists of hexagonal rings in two dimensions.
 The C–C covalent distance in rings is 141.5 pm, indicating strong bonding.
 These arrays of rings form layers. The layers are separated by a distance of 340 pm.
