    so if hydrogen bond is weaker than ionic/covalent bond .....chlorine is a covalent bond right so shouldn't it be stronger than hydrogen bond??

      Erm bonding between atoms (covalent n ionic) will always be stronger than bonding between molecules (van der waals, hydrogen bond)….but for covalent molecules, their melting and boiling point will depend on the van der waals n hydrogen bond, not the covalent bond…so between chlorine molecules only have van der waals (one rope pulling between molecules), whereas between alcohol molecules they have van der waals and hydrogen bond (two ropes between molecules)…so since alcohol have more “ropes” in between the molecules therefore they hav stronger forces and will require more heat energy to break the bonds between molecules….so tat is why those tat can form hydrogen bonds will have higher melting and boiling point compared to those that can only form van der waals..
