The boiling point of HF is 19.5 and the boiling point for HCI is -85. Which of the following answers is the best explanation for the difference in these boiling points. O The hydrogen bonding between molecules of HF are stronger than the hydrogen bonding forces between molecules of HCI. O The hydrogen bonding between molecules of HF are stronger than the dipole-diopole forces between molecules of HCI. O This is because the F atom in HF has less electrons than the CI atom in HCI. O This is because the dispersion forces between HCI molecules are weaker than the dispersion forces between HF molecules.
