Electrophilic substitution is the counterpart from the nucleophilic substitution in the attacking atom or molecule, an electrophile, has low electron density and therefore a optimistic cost. Typical electrophiles tend to be the carbon atom of carbonyl teams, carbocations or sulfur or nitronium cations.
