(Chemistry) a weak chemical bond between an electronegative atom, such as fluorine, oxygen, or nitrogen, and a hydrogen atom bound to another electronegative atom. Hydrogen bonds are responsible for the properties of water and many biological molecules ...
Hydrogen bonds are found in nucleic acids between base pairs and between water molecules. Hydrogen bonds also form between hydrogen and carbon atoms of different chloroform molecules, between hydrogen and nitrogen atoms of neighboring ammonia molecules, between repeating subunits in the polymer nylon, an...
In the liquid state, the hydrogen bonds of water can break and reform as the molecules flow from one place to another. When water is cooled, the molecules begin to slow down. Eventually, when water is frozen to ice, the hydrogen bonds become permanent and form a very specific network. Fi...
Now you know how and why hydrogen bonds form and how to identify donor and acceptor atoms within a hydrogen bond. Did you find this article helpful? Let us know in the comments section below. Or check out more articles in ourChemistry for Biologistschannel. ...
(the answer is "false") I've read that hydrogen bonds are broken upon ebulition, for example. Can I say that there is a change in force as for hydrogen bonds in solids and liquids too? In other words, can I say that the hydrogen bond is stronger in lliquids than in solids or vic...
where H is explicitly involved in the interaction. Nevertheless, H-bonding is not an on–off phenomenon but is a graduated scale which makes quantifying and clearly demarking H-bonding difficult. The low strength of (most) H-bonds in ILs makes them dynamic, able to form and break at room...
Hydrogen bonds are of outstanding importance for many processes in Chemistry, Biology, and Physics. From the theoretical perspective the small mass of the proton in a hydrogen bond makes it the primary quantum nucleus and the phenomena one expects to surface in a particular clear way are, for ...

where the energy minimum is found for a non-planar conformation with H-O-H angles of 116.6° and O-H distances of 0.96 Å. The effect of an external field is essentially to lengthen the O-H distances and decrease the H-O-H angles in order to form approximately linear hydrogen bonds....
