Classify (E,Z,Z,Z,Z,Z,Z)-[14]annulene, in which the inner hydrogens clash and force the ring out of plane (do not assume planarity) as aromatic, anti-aromatic or non-aromatic.

Question

TestHub · Accepted Answer

The ring cannot stay planar because of the H...H clash, so the cyclic π overlap is broken and no aromatic stabilisation arises. Non-aromatic.
