difference between anti-aromatic and non-aromatic?

I know anti-aromatic doesn't follow Hund's rule, is non-aromatic something that lacks sp2 orbitals all around? Can someone clear that one up for me?

(4n+2pi)

When you get n as a fraction, it is anti.

non aromatic does not follow that equation. n is not integer or fraction in this case.

Also non aromatic contains sp3. Correct me if am wrong!🙂

The rules for anti-aromaticity are basically the same as aromaticity except instead of 4n +2 pi electrons you want 4n.

- needs to be conjugated
- needs to be planar
- needs to be cyclic
- 4n pi electrons

Oh and Im not sure how big is too big, but bigger molecules might not follow these rules b/c they can fold too much meaning they would not be planar 👍

Once you hit like 10 carbons you have started to lose planarity (if that is a word). But then you can regain it with bridges that form on their own...it gets complicated.
