If it’s hard to visualize azulene as aromatic, it might be helpful to draw a resonance form where both rings look like they have aromatic components. For example, in the resonance form below, you can think of azulene as being composed of the cycloheptatriene cation (aromatic) fused to the...
Step-by-Step SolutionStep 1: Definition of Aromatic Compounds Aromatic compounds are a class of compounds that are characterized by their cyclic structure, planar geometry, and the presence of delocalized pi el
adjacent p orbitals. The pi-electron count is defined by the series of numbers generated from 4n+2 where n = zero or any positive integer (i.e., n = 0, 1, 2, etc.). This rule is known as Huckel’s rule. It is used to identify the aromaticity of the ring-shaped planer molecul...

Huckel’s Rule of Aromaticity:All compounds must obey Huckel’s Rule i.e. molecule must have 4n+2 pi-electrons where n is an integer (i.e. n= 0, 1, 2, 3, 4…etc.). For example, Benzene has 6 pi-electrons and (4×1)+2 = 6, thus it obeys Huckel’s Rule while cyclooctate...
