(a)
Interpretation:
The aromatic cyclopolyenes that are neutral are to be predicted.
Concept introduction:
A molecule must be cyclic, planar, completely conjugated and should follow Hückel’s rule to be classified as aromatic. According to the Hückel’s rule, the number of

Interpretation:
The aromatic cyclopolyenes that have single negative charge are to be predicted.
Concept introduction:
A molecule must be cyclic, planar, completely conjugated and should follow Hückel’s rule to be classified as aromatic. According to the Hückel’s rule, the number of
(c)
Interpretation:
The aromatic cyclopolyenes that have double negative charge are to be predicted.
Concept introduction:
A molecule must be cyclic, planar, completely conjugated and should follow Hückel’s rule to be classified as aromatic. According to the Hückel’s rule, the number of
