i do not kno the answer that is why i am asking
It is much easier to get a question answered, if you don't "non-answer" it yourself.
Perhaps that helps.
Ionic compounds have a higher melting point.
a lower melting point
Ionic compounds contain ionic compounds whereas molecular compounds contain covalent bonds in their molecules.
In molecular compounds, atoms are joined by covalent bonds, while in ionic compounds, they are joined by ionic bonds.

The melting and boiling points of molecular compounds are generally quite low compared to those of ionic compounds. This is because the energy required to disrupt the intermolecular forces between molecules is far less than the energy required to break the ionic bonds in a crystalline ionic compound
Many ionic compounds exist as crystals but covalent compounds as molecules (there are exceptions as diamond though). Ionic compounds would be good electrical conductors unlike molecular compounds.

Ionic compounds have higher melting and boiling points than molecular compounds do. The electronegativity difference in ionic compounds makes their bond much stronger.
Ionic compounds conduct electricity while molecular compounds do not
