Question

Which statement is correct for cycloctatetraene?

• A. It follows $4n\pi$ electrons Huckel rule and is antiaromatic
• B. It is much more stable than open chain analogue
• C. It lacks coplanarity
• D. It is a flat molecule

Answer 1

The correct option is C 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.
