Question
Which group forms the strongest H-bonds to water molecules?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Phenols form the strongest hydrogen bonds with water because the O-H bond is more polarized (more acidic) due to resonance stabilization of the phenoxide ion, making the hydrogen more partially positive and thus a better hydrogen bond donor.
Hint
Which compound has the most polarized O-H bond?
