WebNov 29, 2024 · Hydrogen Bonding is the formation of Hydrogen bonds. Hydrogen bond is an electrostatic force of attraction between a hydrogen atom and an atom containing a lone pair of electrons in a chemical substance. Hydrogen bonding is major of two types of intramolecular and intermolecular hydrogen bonding

In a hydrogen bond, the electronegative atom not covalently attached to the hydrogen is named the proton acceptor, whereas the one covalently bound to the hydrogen is named the proton donor. While this nomenclature is recommended by the IUPAC, in the hydrogen bond donor, the H center is protic. The donor is a Lewis base. Hydrogen bonds are represented as H···Y system… WebHydrogen sulfide has a much lower boiling of − 6 1 ∘ C, because hydrogen sulfide molecules cannot induce the formation of any hydrogen bonds whatsoever. It takes a lot of energy to separate water molecules, because they are held together with strong hydrogen bonds.
