CaCl2 is ionic, is solid and will have the highest melting point. The rest are covalent compounds.
there are number of compounds having covalent bond and high melting point. Most common example is-diamond (Made of C)
Covalent bonds do not melt. Compounds with covalent bonds melt and the melting point depends primarily on whether there are discrete molecules held together by intermolecular forces (which have lower melting points) or giant covalent networks such as in silica or diamond (which tend to have higher melting points).
Molecular Solids have a lower melting point
Generally the ionic molecules has a higher melting point.

Diamond is a covalent network solid, and those types of compounds have higher melting points than other types of compound.

Diamond is an allotrope of carbon where all the carbon atoms are tetrahedrally bonded with each other forming a three dimensional covalent network. Since the bonds are strong (covalent, network), diamond has a very high melting point and boiling point. Iodine does not have three dimensional network and hence has very low melting/ boiling point. It fact, it will sublime at room temperature.
No. "A lot of energy is needed to separate the atoms in diamond. This is because covalent bonds are strong, and diamond contains very many covalent bonds. This makes diamond's melting point and boiling point very high. There are no free electrons or ions in diamond, so it does not conduct electricity"(BBC).

This is the covalent bond.
It is because of the fact that diamond has stronger covalent bond between C-C atoms and it requires large amount of energy to break the bonds.
