Based on your knowledge of electrophilic aromatic substitution,and assuming the thiophene ring of benzo[b]thiophene (shown)is activated toward electrophilic aromatic substituted more so than the benzenoid ring,predict the preferential position of attack of an electrophile,i.e.,does the electrophile E+ attack carbon 2,or 3? Explain your answer. ![Based on your knowledge of electrophilic aromatic substitution,and assuming the thiophene ring of benzo[b]thiophene (shown)is activated toward electrophilic aromatic substituted more so than the benzenoid ring,predict the preferential position of attack of an electrophile,i.e.,does the electrophile E<sup>+</sup> attack carbon 2,or 3?
