why is cyclopentadiene non aromatic? what happens due to presence of sp3 carbon so that it is non aromatic?
I think you have to make clarity in your question that what you want to ask because cyclopentadiene can be aromatic or not it depends on whether it is cation or anion?
Hope you will understand
It does not have any cation Or anion
It has a sp3 hybridised carbon
Got it thank you
