Question

The molecular interactions responsible for hydrogen bonding in HF

• A. Ion Induced dipole
• B. Dipole-dipole
• C. Dipole Induced dipole
  
• D. None of these

Answer 1

Answer: (B)

Dipole-dipole

A hydrogen bond is formed by a dipole-dipole force between an electronegative atom (the hydrogen acceptor) and a hydrogen atom that attaches covalently with another electronegative atom (the hydrogen donor) of the same molecule or of a different molecule. Only nitrogen, oxygen, and fluorine atoms can interact with hydrogen to form hydrogen bond. Hence the molecular interactions responsible for hydrogen bonding in HF are dipole – dipole interaction.
