Question

Hydrogen fluoride bond is weaker than hydrogen chloride in aqueous solution

Answer 1

HF has the strongest Hydrogen bonding as Fluorine is the most electronegative element whereas in HCl the bonding is comparatively weaker. Hence, it is difficult to take out hydrogen from HF than HCl, which shows HF is weakest acid among halides

Answer 2

Hey !!

It is due to

(a) Higher H ---- F bond dissociation energy than H ---- Cl

(b) Stronger H ---- bonding of F⁻ ion with H₃O⁺ than Cl⁻

Good luck !!
