WebIn fact cyclobutadiene has 4n pi electrons which would make it antiaromatic. And yes it is planar. In fact what happens to avoid this issue: cyclobutadiene will distort into a rectangle with 2 long sides and 2 short sides, this will make more sense if you draw the frost circle for the rectangle. Hopefully that makes sense.

If you are about to construct the MOs for both cycles, you'll find that putting 4n electrons will rise in a diradical molecule, not stable as it already sounds. A quick trick for doing that is using Frost's circle. shweta photo

WebApr 8, 2024 · A compound in a cyclic form that does not demand a continuous form of an overlapping ring of p-orbitals needs not be considered aromatic or even anti-aromatic. Hence, these are termed as non-aromatic or aliphatic. The electronic energy of non-aromatic compounds is the same as its open-chain counterpart.
