Question

Boiling point of hydrogen fluoride is highest amongst HF, HCl, HBr and HI. Which type of intermolecular forces are present in hydrogen fluoride? (A) H— F has highest van der Waals forces and dipole moment. (B) H — F has highest London forces. (C) H— F has highest dipole moment hence has dipole-dipole, London forces and hydrogen bonding. (D) H— F has strong intermolecular interactions like dipole-induced dipole.
