Hydrogen Bond Sites

[Yazmin Bocanegra 3L]

Are hydrogen bond sites defined by how many hydrogen atoms there are branched off of the molecule? Or are there specific properties/conditions that a branched off hydrogen atom must follow to be considered a hydrogen bonding site?

i think it’s just the number

Hydrogen bonding occurs when there is a hydrogen bonded to a N,O, or F atom and is attracted to another N,O, or F atom or vise versa. So, the number of hydrogen bonding sites consists of the number or lone pairs on the N,O or F molecules (because they must essentially share electrons with the H atom) and where there is an H atom. For example, in H2O, the oxygen has two hydrogen bonding sites and the hydrogens each have one.

H bonds are defined by if they are attached to a N,O, or F atom.

[Kallista McCarty 1C]

Hydrogen bonds are only created between a H and a F, O, N (remember it as "phone")

So it's based on the lone pairs available to bond?
