WebAnswer (1 of 2): Cyclopentadiene is not anti-aromatic. It’s just a diene. There are three initial criteria that must be met before we consider electrons in the pi system. To be aromatic (Unusually stable) like cyclopentadienyl anion you must be 1. planar : …
WebExamples of antiaromatic compounds are pentalene (A), biphenylene (B), cyclopentadienyl cation (C). The prototypical example of antiaromaticity, cyclobutadiene, is the subject of debate, with some scientists arguing that antiaromaticity is not a major factor contributing to its destabilization.
