Question

Cycloctatetraene follows the $4n\pi$ electrons Huckel rule for antiaromatic compound but even then it is not antiaromatic compound because -

• A. It is completely planar molecule
• B. It lacks coplanarity
• C. It is a flat molecule
• D. It is much more stable than open chain analogue

Answer 1

The correct option is B It lacks coplanarity

Cycloctatetraene follows the $4n\pi$ electrons Huckel rule for antiaromatic compound but even then it is not antiaromatic compound because it is non-planar, it it adopts a “tub” shape.
