Can sulfur participate in a hydrogen bond?

Members don't see this ad.

I googled it and got both answers, "yes" and "no."

What I mean is: O-H-S, F-H-S, N-H-S, etc.

Ex.'s of "yes": http://www.ncbi.nlm.nih.gov/pubmed/19089987 http://pubs.rsc.org/en/content/articlelanding/2011/ce/c0ce00760a

Ex. of "no": http://www.nature.com/nature/journal/v149/n3773/abs/149218a0.html

Nope. Only F, O, and N. An argument can be made that sulfur is in the same family as oxygen, but that argument doesn't apply to electronegativity (the main periodic trend involved in H-bonding) because electronegativity tends to decrease down a column.

If you're wanting to look at primary literature, non-classical hydrogen bonds (NCHB's) exist as well, but this is making a simple concept overly complicated.

For the MCAT, only FON's can hydrogen bond. End of story.

thank you!
