1.	The boiling point of water (100^(@)C) is much higher than that of HF(19.5^(@)C), even though they have similar molecular masses. Explain.
Answer» SOLUTION :Each water MOLECULE is INVOLVED in intermolecular H-bonding with four other water molecules but each HF molecule is involved in intermolecular H-bonding with two other HF molecules. Therefore, the degree of molecular association in water is much HIGHER than that in HF.
