Doubt from Nucleophile

#1

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

#2

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

#3

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.
