Electrophilic aromatic substitution describes the reaction where a hydrogen from a benzene ring is replaced by an electrophile. Halogenation, nitration, sulfonation, alkylation and acylation are all possible using this type of reaction. The electrophile attacks the pi electrons of the aromatic ring, yielding a benzenonium ion. The substituted aromatic product is obtained when a proton is lost, restoring the aromatic system. If there is a substituent on the aromatic ring...

Question 3. [time 4 + 8 = 12 minutes) (a) i. Both the regioselectivity and the rate of an electrophilic aromatic substitution are affected by the substituents already attached to the benzene ring. Some groups promote substitution at the ortho or para positions, while other groups increase substitution at the meta position. Explain the terms "resonance effect" and "inductive effect" of substituents (use words and schemes). ii. Explain, using words and schemes, how in electrophilic aromatic substitutions existing substituents direct...
