Interpretation: The molecules which are least likely to form a hydrogen bond with a water molecule need to be identified.
Concept Introduction: A hydrogen bond is formed when a molecule with a hydrogen atom attached to an electronegative atom is near a molecule of the same and different kind having a hydrogen atom bonded to an electronegative atom.
Explanation of Solution
Reason for correct option/s:
The given molecule in option (b) is
Reason for incorrect option/s:
The given molecule in option (a) is ammonia. Here, nitrogen is an electronegative atom containing one lone pair. The hydrogen bond is formed when a molecule containing a hydrogen atom bonded with an electronegative atom show bonding with an electronegative atom bonded with the hydrogen atom in the same or different molecule. Here, a hydrogen atom bonded with an oxygen atom in a water molecule can form a hydrogen bond with ammonia.
Thus,
The given molecule in option (c) is HF. Here, F is an electronegative atom bonded with the hydrogen atom. It can show hydrogen bonding with the water molecule.
The given molecule in option (d) is
