Re: Hydrogen Bonding sites
Each lone pair on an oxygen, nitrogen, or fluorine is a potential hydrogen bonding site and each hydrogen that is attached to an oxygen, nitrogen, or fluorine is a potential hydrogen bonding site. For example, water has 4 hydrogen bonding sites (2 lone pairs on oxygen and 2 hydrogens attached to the oxygen).

Re: Hydrogen Bonding sites
Each lone pair on an oxygen, nitrogen, or fluorine is a potential hydrogen bonding site. Also, a hydrogen that is attached to an oxygen, nitrogen, or fluorine is also a potential hydrogen bonding site.
Re: Hydrogen Bonding sites
In organic molecules where they don't show the carbon atoms or lone pairs, do we assume that there are lone pairs around Oxygens or hydrogens...?

You would assume that each atom has however many lone pairs it would need for a complete octet

Re: Hydrogen Bonding sites
Each hydrogen that is attached to either N, O, or F counts as a potential binding site and every lone pair on a N, O, or F atom

Re: Hydrogen Bonding sites
as long as one molecule has O,N,or F it is a potential bonding site as long as there is a Hydrogen on the other molecule

hydrogen bonding sites occur at lone pairs and at hydrogens that are bonded to O N or F (forming a polar hydrogen bond)
Re: Hydrogen Bonding sites
Any hydrogen attached to a F, O , or N , and any lone pairs on those atoms can make hydrogen bonds.

Re: Hydrogen Bonding sites
Hydrogen bonding sites are determined by the number of lone pairs on the N, O, or F atoms. Each lone pair is a potential bonding site.

Re: Hydrogen Bonding sites
Hello! You can tell how many hydrogen bonding sites there are by looking for both acceptors and donors. An acceptor is either a F, O, or N atom with a lone pair. A donor is a F,O, or N atom bonded to a Hydrogen atom. When you are given a compound if you can identify all the donor and acceptor sites then you can figure out how many total bonding sites you have. Hope this helps.
Re: Hydrogen Bonding sites
N,O, or F has to be covalently bound to a hydrogen and have a lone pair for a hydrogen bond to form
