Electrophiles | Nature of Reagents |

• These are called electron-loving species.
• Are electron deficient species or electron acceptor is electrophile.

It is of two types

1. Charged electrophile (E⁺ ): Positively aharged species in which central atom has incomplete octet.

E.g, H⁺ X⁺, NO⁺, R⁺, Fe²⁺

Note: All cations are charged electrophiles except cations of IA, IIA group elements, Al³⁺ and NH₄⁺

2. Neutral electrophile: it can be classified into 3 categories.

• Incomplete octet or vacant d – orbitals containing neutral molecules. (e.g BF₃, BCl₃, AlCl₃, SF₆, SnCl₄ )
• Neutral molecules in which more EN atoms are attach to multiple bonds.(e.g CO₂, SO₂, SO₃ )
• Carbene , Nitrene and carbon free radicals are electrophiles.
