Hydrogen Bonding Sites

[Jorja De Jesus 2C]

What exactly are hydrogen bonding sites? Are they where hydrogen is just bonded to some element or where hydrogen can potentially bond with an element?

[Vanessa Chuang 4F]

Hydrogen bonding sites are any place where hydrogen can potentially bond with an element. This includes both the actual hydrogen atom as well as the lone pairs on the F, O, and N atoms.

[Vicki Liu 2L]

As mentioned, hydrogen bonding sites are places on molecules where a hydrogen bond could be formed. So this could mean one of two things: a N, O, F atom with an available lone pair OR a H atom attached to a N, O, F atom. In the first instance, the lone pair could allow bonding with a nearby hydrogen atom from a different molecule. In the second instance, the H atom could bond with a nearby N, O, or F atom from a different molecule.

[Justin Sarquiz 2F]

In its simplicity, each lone pair around a N, O, or F each count as one hydrogen bonding site. A hydrogen bonded to a N, O, or F also counts as a hydrogen bonding site.

Anywhere where F, O, or N can bond with one another through a Hydrogen atom.

it is anywhere where hydrogen can potentially bond to an element, so anywhere where there is F,O,N

Hydrogen bonding sites are where hydrogen bonding can occur. This includes hydrogen atoms that are bound to electronegative atoms like F, N, or O. A hydrogen bound to one of these elements would be a potential site for hydrogen bonding as well as the nitrogen, fluorine, and oxygen atoms bound to hydrogen atoms. So in a compound like HF, both the hydrogen and the fluorine would be potential hydrogen bonding sites, and in a molecule of water, oxygen and hydrogens would both be hydrogen bonding sites due to their partial charges that result from the difference in electronegativities of the atoms.

Any site where a Hydrogen atom bonds to a Nitrogen, Oxygen, or Fluorine atom.

[Chetas Holagunda 3H]

Hydrogen bonding occurs when there is a covalent bond between a H and F, O, or N, causing a large dipole moment. Then another Hydrogen can bond on the lone pairs of the F, O, or N or another F, O, N can bond to the partially positively charged H.

[Kaitlynn Tran 3F]

It is anywhere that has potential to form a hydrogen bond. Essentially, it is any lone pair on an N, O, or F atom.
