Question

# Which one has the highest melting point?A. Ionic crystalB. Molecular crystalC. Covalent crystalD. Metallic crystal

Note: The melting point of any crystal can be easily determined by its structure. Like, the melting point of the diamond is$\text{355}{{\text{0}}^{o}}\text{C}$. High melting point is because of the presence of strong covalent bonds and formation of a giant three-dimensional network.
