Interpretation:
Whether azulene, an isomer of naphthalene, is
Concept introduction:
According to Huckel’s rule a planar, cyclic conjugated system will be aromatic if it contains (4n+2)Ï€ electrons. Systems with 4nÏ€ electrons will be antiaromatic.
Resonance structures differ only in the position of lone pair or its π electrons. The position of atoms in different resonance forms do not differ. They do not represent the actual structure of the molecule. The actual structure is a hybrid of all the resonance forms possible.
To state:
Whether azulene, an isomer of naphthalene, is aromatic.
To draw:
Another resonance form of azulene in addition to that shown.
