@@Nithyashreejayaraman First, it has 16 electrons if you count them all. Second, you weren't paying attention to what I talked about in the video when I was talking about the MO reorganization in the molecule to avoid being anti-aromatic 😉 Pyrene's molecular orbitals reorganize themselves to make up 2 aromatic rings and 2 independent pi bonds making it perfectly stable. You'll see the same phenomenon in most large polycyclic aromatic hydrocarbons. They would seem anti aromatic if you tally up all electrons, yet they all reorganize themselves in such a way as to avoid it.

Very Helpful. Thanks so much Sir
But please recheck the structure of pyrene once
@@Nithyashreejayaraman Pyrene is fine. It's one of the many resonance structures it has.
Sir, but from the structure, Pyrene seems to have 12 pi electrons which makes it anti aromatic. Hence my query
