Question

The boiling point of methanol is +65 °C; the boiling point of oxygen is –183 °C. Methanol and oxygen each have an Mr value of 32. Explain, in terms of the intermolecular forces present in each case, why the boiling point of methanol is much higher than that of oxygen₃

Answer 1

What explains the higher boiling point of hydrogen fluoride? There is strong hydrogen bonding between HF molecules. The bond energy of HF molecules is greater than in other hydrogen halides.
