WitrynaThe strengths of these attractive forces vary widely, though usually the IMFs between small molecules are weak compared to the intramolecular forces that bond atoms together within a molecule. For example, to overcome the IMFs in one mole of liquid HCl and convert it into gaseous HCl requires only about 17 kilojoules.

WitrynaA higher melting and boiling point indicates that more kinetic energy is required to overcome the IMFs and melt or boil the substance. Examining the melting and boiling points for these halogens shows a trend that larger and heavier atoms display stronger IMFs, as shown by the higher melting and boiling points. Table 1. WitrynaCH3Cl is a polar molecule because the chlorine is far more electronegative than the carbon atom. Since it is polar, it will have a permanent dipole and dipole-dipole interactions will be the strongest intermolecular forces. It cannot form hydrogen bonds because hydrogen atoms are not bonded to N, O, or F atoms. WitrynaTypes of Intermolecular Forces. An intermolecular force is an attractive force that arises between the positive components (or protons) of one molecule and the negative components (or electrons) of another molecule. Various physical and chemical properties of a substance are dependent on this force. The boiling point of a substance is ... earring leverback pearl
