This means that naphthalene has less aromatic stability than two isolated benzene rings would have. Hence, bond 1 and 2 have higher bond order and less anti-bonding charectaristics. ii) Regioselectivity when electrophilic aromatic substitution of anthracene takes place iii) Sulpbonation of naphthalene gives different isomers at low and high temperature iv) Reaction outcomes of methylbenzene and 2-methylnaphthalene on oxidation respectively Nomenclature and structure. Polycyclic aromatic hydrocarbon Benzene has six pi electrons for its single aromatic ring. Why Transcribed image text: 5. Thats why benzene prefers electrophilic substitution rxn. This means that naphthalene has less aromatic stability than two isolated benzene rings would have.
