Question 16
Chemical BondingThe boiling point of water is higher than that of methanol because
- A.water is an oxide while methanol is an alcohol
- B.inter-molecular forces in water are stronger than those in methanol
- C.water is an inorganic compound while methanol is organic
- D.water is an ionic compound while methanol is a covalent compound
- E.water is more reactive than methanol
Show the answer and explanation
Answer: B (inter-molecular forces in water are stronger than those in methanol)
Explanation
Water molecules form more hydrogen bonds with each other than methanol molecules do, so more energy is needed to separate them.
