11.0 Nucleophiles

  General Organic Chemistry

Nucleophiles mean nucleus loving species. Nucleophiles are electron donor species. Nucleophilic reagents tend to attack the electron deficient species (electrophiles).

Classification of nucleophiles:

(a) Negative charge species

(b) Organometallic reagent

(c) Lone pair containing species

(d) $\pi -$ bonded molecules

Note: Some species behave as the electrophiles as well as nucleophiles.

Example: $Cl_2, Br_2, I_2$.
