WebCorrect option is B) Option B is the correct answer. Both H 2O and HF have electronegative oxygen and fluorine atoms respectively in their molecule. In fact, Fluorine is more electronegative than Oxygen, so technically, HF should engage in more hydrogen bonding than water. But the scenario is different. Each water molecule has two hydrogen atoms. Web24 de fev. de 2024 · I was expecting $\ce{HF}$ to have highest boiling point because F is the most electronegative atom hence should form stronger H Bonds. Now, I think the factor here might be number of H Bond rather than strength of H Bond. $\ce{H2O}$ have 2 lone pair and 2 H atoms, hence it can form 4 H Bonds with surrounding molecules.
