How does melting point compare among molecular compounds and ionic compounds?

Most of the time, the melting points of ionic compounds are very high compared to the melting points of molecular compounds.

Explanation:

In chemistry, molecular compounds are those compounds that have covalent bonds between their (intramolecular) atoms. These compounds have a lower melting point than ionic compounds and this is because the boiling temperature of a molecular compound is much lower than that of an ionic compound.

Compounds formed by ionic bonds are called ionic compounds. These compounds have a much higher melting point than molecular compounds, because the boiling point of these compounds is much higher than the boiling point of molecular compounds.
