why benzene dosent undergo electrophilic addition reaction?

Expert Answer:

In an addition reaction, electrons from the delocalised system would need to bond to the atom or group of atoms being added. This would result in a product less stable than benzene therefore not energetically favourable because saturating the carbon-carbon bonds destroys the delocalised pi electron cloud. Hence, benzene undergoes substitution reactions in which the product formed retains delocalisation, and hence stability of the benzene ring.
