Question

Which of these molecules experience hydrogen bonding?. . A. hydrogen molecule. B. nitrogen molecule . C. water molecule . D. fluorine molecule . E. methane molecule

Answer 1

Water molecule experience hydrogen bonding.

Step-by-step explanation:

Hydrogen bond is an interaction (secondary) in the molecules having a hydrogen directly bonded to a highly electronegative element (fluorine, oxygen or nitrogen) with another highly electronegative element (fluorine, oxygen or nitrogen) .

The hydrogen bond can be inter-molecular or intra-molecular.

This interaction is due to polarity. the highly electronegative group makes hydrogen attached slightly positive and itself becomes slightly negative.

Answer 2

The correct answer is option C. Water molecules exhibit hydrogen bonding. Hydrogen bonding is the attraction between polar groups that occurs when a hydrogen (H) atom bound to a highly electronegative atom.
