WebThe following is a relatively minor point, but IMHO, the Gobbi hydrogen bond acceptor definition probably should be modified so that only aromatic nitrogen atoms with two and not three non-hydrogen attachments are considered as acceptors. For example, the aromatic nitrogen atom pyridine is an acceptor whereas the nitrogen in indole or N ... WebApr 30, 2016 · This is exactly analogous to amide nitrogen atoms which are also not hydrogen bond acceptors.

Why does a hydrogen bond occur? Since the hydrogen donor (N, O, or F) is strongly electronegative, it pulls the covalently bonded electron pair closer to its nucleus, and away from the hydrogen atom. WebYou also want these electronegative atoms to be small the that donor and acceptor can approach each other more closely adding to the strength of the hydrogen bond. Usually this means atoms like fluorine, oxygen, and nitrogen, but this can also include atoms like carbon, chlorine, and sulfur. bing rewards auto searcher bot
