WebExtra ring strain in cyclopentadienone is not the answer. Delocalization of the positive charge now takes place in a cyclic ring of p orbitals, but the cyclopentadienyl cation is antiaromatic (4n pi electrons), so it is very unfavorable to have CO single bond character, and the C=O stretching frequency is correspondingly high.

WebIn chemistry, pi stacking (also called π–π stacking) refers to the presumptive attractive, noncovalent pi interactions (orbital overlap) between the pi bonds of aromatic rings. However this is a misleading description of the phenomena since direct stacking of aromatic rings (the "sandwich interaction") is electrostatically repulsive.
