10. In chapter 18, we learned that benzene (the most prevalent aromatic ring) reacts with good electrophiles in electrophilic aromatic substitution (EAS) reactions. In chapter 17, we learned there are many other aromatic rings other than benzene. These other aromatic rings can participate in EAS reactions much the same way. The following is an EAS reaction with pyrrole as the starting nucleophile. Draw the complete, detailed mechanism for the formation of the given major product. Include all resonance structures in the sigma complex. BC13

Transcribed Image Text:10. In chapter 18, we learned that benzene (the most prevalent aromatic ring) reacts with good electrophiles in
electrophilic aromatic substitution (EAS) reactions. In chapter 17, we learned there are many other aromatic rings
other than benzene. These other aromatic rings can participate in EAS reactions much the same way. The following
is an EAS reaction with pyrrole as the starting nucleophile. Draw the complete, detailed mechanism for the
formation of the given major product. Include all resonance structures in the sigma complex.
BC13
Expert Solution
Step 1 Theory
Electrophilic substitution reaction in pyrrole takes place at position-2 because attack at position-2 give more number of resonating structures.
Lewis acid helps in the generation of electrophile RCO+
