Assertion (A): Pyrrole, is aromatic and undergoes electrophilic aromatic substitution extremely readily and predominant by at position adjacent to nitrogen.
Reason (R): Nitrogen in the ring bearing a lone pair in conjugation with -electrons brings aromaticity to the pyrrole.
Reason (R): Nitrogen in the ring bearing a lone pair in conjugation with -electrons brings aromaticity to the pyrrole.
View answer and explanation
Correct option: B
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
