How do the melting points boiling points and conductivity of molecular compounds compare to those of ionic compounds?
Molecular compounds have lower melting points, lower boiling points and lower conductivity than ionic. This is because the ionic compounds are giant lattice compounds hef together with electrostatic forces which when dissolved or mlten have free ions that can conduct electricity. Molecular compounds in th eliquid and solid are held together with weak intermolecuar forces, (van der Waals) and when molten or dissolved are uncharged so that they do not conduct.
