"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… " - Describe what a hydrogen bond is

Because of its polarity and ability to form hydrogen … Webdescribe why hydrogen bonds form between water molecules Water molecules are made up of two hydrogen atoms and one oxygen atom. They share a covalent bond within one water molecule. Water molecules are polar which means that oxygen atoms are more electronegative than when compared to hydrogen atoms.

WebHydrogen bonding is an important factor in determining the 3D structures and properties that are acquired by synthetic and natural proteins. Hydrogen bonds also play an important role in defining the … WebHydrogen bonds are intermolecular forces; covalent and ionic bonds are intramolecular forces. Explanation: Ionic Bonds Ionic bonds form when one atom transfers electrons to another atom. The atom that loses an electron becomes a positive ion. The atom that gains an electron becomes a negative ion.
