Fluorine as a hydrogen-bond acceptor: experimental evidence …

In chemistry, a hydrogen bond (or H-bond) is a primarily electrostatic force of attraction between a hydrogen (H) atom which is covalently bound to a more electronegative "donor" atom or group (Dn), and another electronegative atom bearing a lone pair of electrons—the hydrogen bond acceptor (Ac). Such an interacting system is generally denoted Dn−H···Ac, where the solid line denot… WebScience. Chemistry.

WebJul 19, 2024 · Explanation: A hydrogen bond is defined as a weak bond that is formed between an electropositive atom (generally hydrogen atom) and an electronegative atom like oxygen, nitrogen and fluorine. This bond is formed due to difference in the electronegativity of atoms present in a compound which contains a hydrogen bond.
