Why do molecular compounds have low melting points and low boiling points relative to ionic substances?

  • chemistry - ,

    Most molecular compounds are composed of discrete molecules whereas ionic compounds are composed of a three dimensional array of ions. To melt an ionic compound the attractive forces of the crystal must be broken. There are some exceptions to this rule; e.g., diamond is very hard but it is composed of carbon in a network of covalent bonds.
