The melting points and boiling points of molecular covalent compounds (ones with discrete molecules) are lower than ionic solids and giant molecule covalent compounds like (silica, SiO2) because the forces that attract them together in the solid and the liquid states (van der waals, hydrogen bonding and dispersion forces) are weaker than ionic (or covalent) bonds.
The bonds in the molecule are weaker.
no, they are two different things. molecular compounds have a lower boiling and melting point relative to ionic.
Ionic compounds have higher melting and boiling points than molecular compounds do. The electronegativity difference in ionic compounds makes their bond much stronger.
Ionic bonds are significantly resistant to heat, while molecular bonds are broken more easily with the addition of heat energy. Due to this, ionic compounds have much higher boiling points than molecular substances in most cases.

false they tend to have low boiling points
KCl is an ionic compound and glucose is a molecular compound. Ionic compounds have higher boiling points than molecular compounds.
This is false. Ionic compounds have higher boiling points than molecular compounds. For example, the boiling point of the ionic compounds copper(II) oxide, CuO, and sodium chloride, NaCl are 2,000 degrees C and 1,413 degrees C, respectively. The boiling point of the molecular compounds carbon tetrachloride, CCl4, and water, H2O are 76.72 degrees C and 100 degrees C, respectively.
they have diferent temp. also the ionic compounds dont melt they steam
Yes, molecular solids have relatively low melting points.
Due to strong dipole dipole interaction
Because have lower melting points and boiling points
