Which of the following statements regarding the hydrogen bonding in ortho-nitrophenol and para-nitrophenol is correct?
- A.Ortho-nitrophenol exhibits intermolecular hydrogen bonding.
- B.Para-nitrophenol exhibits intramolecular hydrogen bonding.
- C.Ortho-nitrophenol has a lower boiling point than para-nitrophenol due to intramolecular hydrogen bonding.
- D.Para-nitrophenol has a lower boiling point than ortho-nitrophenol due to intermolecular hydrogen bonding.
Show correct answer & step-by-step solution
Correct answer: C — Ortho-nitrophenol has a lower boiling point than para-nitrophenol due to intramolecular hydrogen bonding.
Solution
- Ortho-nitrophenol forms intramolecular hydrogen bonds between the hydroxyl group and the nitro group.
- Para-nitrophenol forms intermolecular hydrogen bonds between different molecules.
- Intermolecular hydrogen bonding leads to association, increasing the boiling point of para-nitrophenol.
- Hence the answer is (C).
