Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Hydrogen bonding with water requires a molecule to have a highly electronegative atom (N, O, or F) bonded to hydrogen, or a lone pair on such an atom to interact with water's hydrogen.

HCOOH (Formic Acid) contains polar –OH and C=O groups that form strong hydrogen bonds with water molecules.

HF (Hydrogen Fluoride) is highly polar and capable of forming direct hydrogen bonds with water due to the high electronegativity of fluorine.

CH₄ and C₆H₆ are non-polar hydrocarbons and lack the necessary polar groups to bond with water.
