- #11What are the necessary conditions for any system to be aromatic?
Ans : A compound is said to be aromatic if it satisfies the following three conditions:
-(i) It should have a planar structure.
(ii) The ``\pi``-electrons of the compound are completely delocalized in the ring.
(iii) The total number of ``\pi``-electrons present in the ring should be equal to (4n + 2), where n = 0, 1, 2 ... etc. This is known as Huckel’s rule.
