Which one of the following does not show hydrogen bonding?
Correct answer: D. Diethyl ether
- A. Water
- B. Ethyl alcohol
- C. Phenol
- D. Diethyl ether
Explanation
Hydrogen bonding requires hydrogen bonded to a highly electronegative atom such as O, N or F, and a lone pair on a neighbouring molecule. Diethyl ether has oxygen lone pairs but no O-H bond, so it cannot hydrogen-bond with itself; students may choose phenol by overlooking its O-H group.

About Hydrogen Bonding
Hydrogen bonding is the strong attraction between hydrogen attached to nitrogen, oxygen or fluorine and an electronegative atom in the same or another molecule. It explains unusual boiling points, viscosity, surface tension, water's properties and the difference between intermolecular and intramolecular hydrogen bonding.
