Question
Use the information and data given below:
• Stronger intermolecular forces result in higher boiling point.
Which type of intermolecular forces are present in the molecules \[\ce{HF, HCl, HBr and HI}\]?
Solution
\[\ce{HCl, HBr and HI}\] have dipole-dipole and london dispersion interaction whereas \[\ce{HF}\] has hydrogen bonding in addition (due to the high electronegativity of the F atom).
