Azulene

Vedclass · Answer

(A) An aromatic compound must follow $H$ückel's rule,which states that the compound must be cyclic,planar,fully conjugated,and contain $(4n+2) \pi$ electrons,where $n$ is an integer $(n = 0, 1, 2, ...)$.$A$. Azulene consists of a seven-membered ring fused to a five-membered ring. It has $10 \pi$ electrons $(n=2)$,is planar,and cyclic,making it aromatic.$B$. This structure is a derivative of azulene,but the specific structure shown is not the standard aromatic azulene.$C$. Pentalene has $8 \pi$ electrons ($4n$ system),making it anti-aromatic.$D$. Cyclobutadiene has $4 \pi$ electrons ($4n$ system),making it anti-aromatic.Therefore,the correct aromatic compound is Azulene.
