Chemistry - Halogen Derivative Question with Solution | TestHub

Nucleophiles are the species which have tendency to donate a pair of electrons. They can be neutral or negatively charged. The nucleophilic power depends on the tendency of species to donate the electrons. Due to the presence of $+\mathrm{I}$ effect, it increases. Hence, higher the $+\mathrm{I}$ effect, higher the nucleophilic power.
