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

substances with strong bonds have high melting points substances with weak bonds have low melting points strong bonds have low potential energy weak bonds have high potential energy the ionic bond is stronger than the covalent bond, and takes more energy to break it apart. Intermolecular forces among molecular compounds are usually quite weak, consisting …
