Answer 2

The correct answer is option (B) Intermolecular H-bonding.

Explanation:

• The common feature among the molecules HF, H20, HCl and NH3 is Intermolecular H-bonding.
• Hydrogen bonding is an intermolecular force which occurs between two molecules which have a hydrogen atom directly bonded to a nitrogen, oxygen, or fluorine atom.
• It is formed when hydrogen atom is in between the two highly electronegative atoms present within the same molecule.
• So no, two hydrogen atoms alone cannot form/engage in hydrogen bonding.
