CH3OH Nucleophile (??)

Postby katknight » Wed Mar 09, 2016 6:41 pm

Why is CH3OH a nucleophile? When you draw the structure, O has two lone pairs; however, O can only form two covalent bonds. I'm very confused as to how it can be explained to be a nucleophile.

it is a nucleophile because the lone pairs repel electrons

Because of the structure of the CH3OH molecule, it is technically protic (meaning that it readily donates hydrogen ions). It can be identified as protic because of the O-H bond present in the molecule. Additionally, this molecule is polar (as it is an alcohol). Therefore, because it donates hydrogen ions, it also donates electrons (i.e. it is considered a nucleophile).
