In which of the following compounds hydrogen bonding is possible?
Correct answer: C. NH3
- A. PH3
- B. CH4
- C. NH3
- D. SiH4
Explanation
Hydrogen bonding occurs when hydrogen is bonded to a highly electronegative atom such as nitrogen, oxygen, or fluorine, which creates a significant dipole. In NH3 (ammonia), hydrogen is directly bonded to nitrogen, which is highly electronegative and capable of forming hydrogen bonds with other molecules. The other options, PH3, CH4, and SiH4, involve atoms that are not sufficiently electronegative to facilitate hydrogen bonding.

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.
