Answer:
HF ≥ H₂O because the HF bond is more polar than the OH bond.
Explanation:
Electrons in the bond will not be shared equally. Hydrogen electronegativity value is 2,1 but Fluorine is 4, so electrons in the covalent bond will be more attracted to Fluorine. The electron cloud will be more distorted towards Fluorine.
I hope this is correct, and as always, I am joyous to assist anyone at any time.
