WebA hydrogen bond is an intermolecular force (IMF) that forms a special type of dipole-dipole attraction when a hydrogen atom bonded to a strongly electronegative atom exists in the … WebHydrogen bonding refers to a unique kind of dipole-dipole attraction between the molecules. It arises due to the attractive force between the atom of hydrogen covalently bonded with a very electronegative atom like oxygen, nitrogen, or fluorine.

Hydrogen bonding plays an important role in determining the three-dimensional structures and the properties adopted by many synthetic and natural proteins. Compared to the C−C, C−O, and C−N bonds that comprise most polymers, hydrogen bonds are far weaker, perhaps 5%. Thus, hydrogen bonds … Meer weergeven 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 … Meer weergeven The concept of hydrogen bonding once was challenging. Linus Pauling credits T. S. Moore and T. F. Winmill with the first mention of the hydrogen bond, in 1912. Moore and Winmill used the hydrogen bond to account for the fact that trimethylammonium … Meer weergeven A symmetric hydrogen bond is a special type of hydrogen bond in which the proton is spaced exactly halfway between two identical atoms. The strength of the bond to each of those atoms is equal. It is an example of a three-center four-electron bond. … Meer weergeven Hydrogen bonding is a relevant to drug design. According to Lipinski's rule of five the majority of orally active drugs have no more than … Meer weergeven Definitions and general characteristics 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 … Meer weergeven Water A ubiquitous example of a hydrogen bond is found between water molecules. In a discrete … Meer weergeven The hydrogen bond can be compared with the closely related dihydrogen bond, which is also an intermolecular bonding interaction involving hydrogen atoms. These … Meer weergeven Web24 aug. 2024 · Hydrogen bonds have been receiving increasing attention by scientists since 1989 when Peter Atkins stated that “hydrogen bonding, a noncovalent interaction in structural organic chemistry, is a link formed by a hydrogen atom lying between two strongly electronegative atoms” (Atkins, 1989). http://web.thu.edu.tw/hclu/www/biochem/Exercise02.doc fal a321
