http://www.biology.arizona.edu/human_bio/problem_sets/blood_types/rh_factor.html WebA nucleophile is a chemical species which, in relation to a response, gives an electron pair to form a chemical bond. Any molecule, ion or atom that is in some manner deficient in electron can act as an electrophile. A nucleophile is usually negatively charged or neutral with a lone pair of electrons. H 2 O, -OMe or -OtBu are some examples.

WebSo strong bases make good nucleophiles. Sulfur is a larger atom than oxygen, making its electrons more polarizable. Thus, it is a stronger nucleophile than oxygen. However, the pka of R-SH is 8.2 where as the pka of R-OH is 16. Thus, the SH group is a stronger acid than the OH. How can sulfur be both a stronger acid and a stronger base than oxygen? WebJul 25, 2014 · $\begingroup$ Do you mean "nucleophilicity" or "electrophilicity"? I associate the power of a compound to act as a nucleophile with the term nucleophilicity whereas you included the "order of reactivity towards nucleophiles" in your question which is a measure of electrophilicity.
