Use the information and data given below to answer the question: • Stronger intermolecular forces result in higher boiling point. • Strength of London forces increases with the number of electrons in the molecule. Which of the following statements best explains why hydrogen fluoride (HF) has the highest boiling point among HF, HCl, HBr, and HI?

Options

1. AHF has the highest dipole moment due to the highest electronegativity of fluorine and the presence of hydrogen
2. BHF has the lowest number of electrons in its molecule, leading to stronger intermolecular forces.
3. CHCl has the lowest dipole moment due to the lowest electronegativity of chlorine.
4. DHI has the highest boiling point because of its larger molecular size.
