Answer:

Because covalent bonds are strong, diamond contains many covalent bonds. As high temperatures are required to break such strong bonds, diamond melts at a very high temperature.The three-dimensional arrangement of carbon atoms, held together by strong covalent bonds, makes diamond very hard. ... Diamond has a very high melting point because a large amount of energy is needed to overcome the many strong covalent bonds.
