Question

which is strongest nucleophile, OH- or C2H5O-

Answer 1

Which is the best nucleophile, C2H5O or ammonia? Ammonia is the better nucleophile as positive charge is relatively more stable on nitrogen atom than on oxygen atom due to higher electronegativity of oxygen. This fact is supported by the evidence that when nh3 is dissolved in water we get NH4+ and oh- and not NH2-

OH - The Nucleophile/Base — Master ... Whether something is a nucleophile or a base depends on the type of bond it is forming in the reaction. Take a species like NaOH. It's both a strong base and a good nucleophile. ... Similarly, when it's forming a bond to carbon (as in a substitution reaction) we say it's acting as a nucleophile.

Answer 2

C2H5O IS STRONGER BECAUSE OF + I EFFECT SHOWN BY C2H5
