Hey there!
Covalent Compounds are made between non-metals with either same or slightly different electro-negativities and thus have low melting & boiling points because they have weak forces of attraction between the binding molecules, thus less energy is required to break the force of bonding.
Ionic compounds are made between metals & non-metals with large difference in their electro-negativities and thus they have high melting & boiling points because there exists a strong force of attraction between the oppositely charged ions, so a large amount of energy is required to break the strong bonding forces between the ions.

Hey!
Here is your answer.
If we see , In the case of ionic compounds, there is a complete transfer of electrons from one atom of the element to another atom of another element. Hence it's sure that there exists a strong electrostatic force between them.
If we see in the case of covalent compounds, electrons are not completely dragged, the atoms of different elements are attracted by a weaker electrostatic force.
Thus, ionic compounds have atoms bounded by stronger electrostatic force than in case of covalent compounds. So, its sure that , in general it is easy to break covalent bond than ionic.
Thus, melting point of ionic compounds is greater than covalent compounds or we can say that covalent bonded compounds have lower melting point and ionic compounds have a higher melting point.
Thanks!
This is the answer.
I hope it helps you.!!
