Question

According to Huckel's rule, a cyclic, planar, fully conjugated system is strictly classified as anti-aromatic if its $\pi$ electron cloud contains exactly:

Prashant Kotian · Accepted Answer

Correct answer: B. Anti-aromaticity occurs when a continuous planar conjugated circuit contains electrons (e.g., 4, 8, 12). This quantum state is exceptionally unstable. yields aromaticity. An carbon breaks conjugation entirely, yielding non-aromaticity.
