Based on electronegativity and orbital interactions, which of the following hydrogen bonds is experi — Chemical Bonding Chemistry Question

💡 Solution & Explanation

The strength of a hydrogen bond increases with the electronegativity of the atoms involved. Fluorine is the most electronegative element, creating the largest partial charges. Thus, the $F-H \cdots F$ hydrogen bond (found in $HF$ and $KHF_2$) is the strongest.
