WebWeak nucleophiles are generally, neutral and don't bear a charge. Some examples are CH3OH, H2O, and CH3SH. There is always a close relationship between nucleophilicity and basicity. As a rule of thumb, when a compound is a strong base, it is a strong nucleophile, too: typical examples are the OH¯/H₂O or CH₃O¯/CH₃OH pairs, in which the ...
