Which type of intermolecular attractive force is responsible for the anomalously high boiling point of water compared to hydrogen sulfide ()?
Answer and explanation
Correct answer: B. Intermolecular hydrogen bonding
- Step 1: Oxygen has high electronegativity and small atomic radius, enabling strong hydrogen bonds between water molecules. Step 2. Sulfur has lower electronegativity and cannot establish significant hydrogen bonding, so is a gas at room temperature while water is a liquid. Answer: Intermolecular hydrogen bonding. Why not the others: Hydrogen bonding accounts for water's anomalous boiling point.
