WebApr 27, 2015 · 1 Answer Sorted by: 17 Essentially it's a case of aromaticity vs number of resonance structures. Well put! Aromaticity is a very strong driving force so aromaticity wins out; Huckel's rule is more important than the number of resonance structures. Therefore cyclopentadiene is more acidic than cycloheptatriene. WebApr 7, 2024 · The structure of cyclopentadiene is shown in the figure below, When it loses a proton, its structure becomes The above structure obeys all the rules of aromaticity. It is cyclic and its planar and has p-orbitals on each atom. To check for Huckel’s rule, we should count the number of pi electrons in the above molecule. There are 2 pi bonds. gay resorts in vegas
