The electrophilic aromatic substitution reaction of furan has to be explained. Concept Introduction: Electrophiles are electron deficient species. In Electrophilic substitution reaction a group or atom in a compound is replaced by electrophile. This kind of reaction occurs predominantly in aromatic compounds . Electrophilic substitution reactions of aromatic compounds are known as aromatic electrophilic substitution reactions. The aromatic five-membered heterocycles all undergo electrophilic substitution , by means of a universal reactivity order: pyrrole >> furan > thiophene > benzene. The reaction situation proves plainly the better reactivity of furan compared with thiophene. While the electrophile attacks C-3 , together furan and pyrrole intermediates will contain two significance structures, on the other hand, stipulation substitution is at the alpha position ( C-2 or C-5 ) reaction intermediates will have three significance structures.
