Question

compare the aromatic nature of pyrrole , furan and thiophene​

Answer 1

Explanation:

Since N is less electronegative than O, it will be slightly more stable than O with that positive charge. Hence, pyrrole will be more aromatic than furan. Therefore, according to me, the aromaticity order should be: benzene > pyridine > pyrrole > furan > thiophene.
