Doubt from Nucleophile


why negatively charged species are stronger nucleophile in comparison to neutral species?


Negative charge implies more density of electrons. Due to this excess, the atom donates electrons more willingly than neutral species, thus negatively charged are more nucleophilic in character than neutral


Let’s talk about neutral and negatively charge particle
Neutral particle has no extra electron so it may give or take electron electron.
A negatively charge particle means it accepted a electron and has more electron density. So it will definitely donate electron so it will attack more rapidly than neutral particle.
Basically necleophile depend upon the charge density.
