Cyclobuta-1, 3- diene is not an aromatic compound because it is in violation of the Huckel rule.
- For aromaticity, there must be (4n+2) π electrons present in the ring.
- But in cyclohexa-1,3-diene, there are only 4 π electrons present inside the ring.
- Moreover, there is not complete delocalisation of π electrons in the ring.
- Hence, it is not an aromatic compound.
