Hydrogen Bonding

Postby salvadorramos3k » Mon Nov 18, 2019 11:16 pm

Can someone please explain where hydrogen bonding occurs? For example, if hydrogen is in the middle of a molecule, can hydrogen bonding still occur or does it have to be on the outer part of the molecule?

In order for a hydrogen bond to form, it must be covalently bonded to Fluorine, Oxygen, or Nitrogen and it must be with a Fluorine, Oxygen, or Nitrogen atom with a lone pair. For example, the hydrogens in H2O interact with the Oxygen in water molecules (which has 2 lone pairs). Also, since Hydrogen only has an s orbital, it can only be on the outside of a molecule (it can only make one bond so it cannot be a central atom).

Hydrogen bonding occurs between Hydrogens that are connected to Nitrogen, Oxygen, and Fluorine

Hydrogen bondings occurs when H bonds to either F, O, or N.

You should also know that h-bonding only occurs when the hydrogen is directly attached to N,O,F.

hydrogen bonding occurs between molecules and it happens with H and F,N, or O

It should also be noted that if O happens to have 2 lone pairs, H-bonding can happen at each of those sites, meaning that O can H-bond twice.

Hydrogen bonding occurs when the hydrogen bonds with N,O or F

Hydrogen bonding occurs between a hydrogen atom that is bonded to N/O/F and a N/O/F atom with at least one lone pair.

As stated by others, hydrogen bonding can only occur with N, O, and F. The hydrogen that is going to bond must bond to one of those three atoms AND must already be bonded to either N, O, or F. Also, hydrogen will never be the central atom so you don't have to worry about that coming up:)
