A hydrogen bond is anelectrostatic attractionbetween an electronegative atom (one that has lone pair electrons) and a hydrogen atom bound to an electronegative atom. Because the electronegative atom has lone pair electrons and steals some electron density from other places, it takes on a partial ne...
Hydrogen bonds are not “true” bonds like covalent and ionic bonds, but rather directional electrostatic attractions between slightly negative and slightly positive atoms. The standard configuration of a hydrogen bond is of the type D— H···A where: H is a hydrogen atom with a partial posit...

A hydrogen bond is a type of intermolecular force of attraction that is a stronger version of the dipole-dipole interaction (also an intermolecular force of attraction). Chemicals with more hydrogen bonds usually have higher boiling points because these hydrogen bo...

aThe hydrogen bond is a weak bond,but than van der Waals force is strong.H2O has two hydrogen atoms.The oxygen atom has two lone pairs of electrons, which is easy to other hydrogen atoms to form hydrogen bonds, so H2O can form four hydrogen bonds.[translate]...
A hydrogen bond (H-bond) is one of the most fundamental and important noncovalent interactions in chemistry, biology, physics, and all other molecular sciences. Especially, the dynamics of a proton or a hydrogen atom in the H-bond has attracted increasing attention, because it plays a crucial...

Ab initio and atoms in molecules (AIM) theoretical studies have been used to show that in a 1:1 complex formed between CH 4 and H 2O, CH 4 acting as a hydrogen bond acceptor leads to the global minimum structure. There is a bond path connecting C to the H of H 2O revealing a ...
I.r. evidence for a strong hydrogen bond in the fluoride-uracil system A new 1 : 1 adduct of KF and uracil has been prepared and its i.r. spectrum reveals the presence of strong asymmetrical N–H ‥ F– hydrogen bonds. James,H.,Clark,... - 《Journal of the Chemical Society Chemica...
