Question

explain hydrogen bonding​

Answer 1

A hydrogen bond (often informally abbreviated H-bond) is a primarily electrostatic force of attraction between a hydrogen (H) atom which is covalently bound to a more electronegative atom or group, particularly the second-row elements nitrogen (N), oxygen (O), or fluorine (F)—the hydrogen bond donor (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 denotes a fully covalent bond, and the dotted or dashed line indicates the hydrogen bond. The use of three centered dots for the hydrogen bond is specifically recommended by the IUPAC.[4] There is general agreement that there is actually a minor covalent component to hydrogen bonding, especially for moderate to strong hydrogen bonds (> 5 kcal/mol), although the importance of covalency in hydrogen bonding is debated. At the opposite end of the scale, there is no clear boundary between a weak hydrogen bond and a van der Waals (e.g., dipole-dipole) interaction.

Answer 2

Answer:

ANSWER ⬇️⬇️

the hydrogen bonding is the type of attractive ( dipole -dipole) interaction between an electronegative atom and a hydrogen atom bonded to another electronegative atom. this bond always involves hydrogen atom.hydrogen bonds can occur between molecules or within part of a single molecule.
