Which of the following is NOT a benzenoid compound?

1. (1) a fused polycyclic aromatic structure (shown)
2. (2) cyclooctatetraene (shown)
3. (3) naphthalene (shown)
4. (4) aniline (shown)

Correct answer: (2) cyclooctatetraene (shown)

Solution

Benzenoid aromatic compounds contain fused or isolated benzene rings (naphthalene, aniline, fused polycyclic arenes). Cyclooctatetraene is an eight-membered ring, tub-shaped and non-aromatic, so it is not a benzenoid compound.
