Incorrect statement regarding aromaticity among the following is:
1. | The compound should have a planar structure. |
2. | The π–electrons of the compound are completely delocalized in the ring. |
3. | The total number of π–electrons present in the ring should be equal to (4n + 2) π electrons, where n = 0, 1, 2 … etc. This is known as Huckel’s rule. |
