Question

4. Naphthalene is aromatic because. A. It has high-resonance energy. B. It contains 10π electrons C. It undergoes substitution rather than addition reaction. D. all is correct

Answer 1

Answer:

D. all are correct

Explanation:

Aromatic compounds are cyclic, planar structures with delocalized pi bonding/resonance. Due to delocalized pi bonding, aromatic compounds like naphthalene have a high resonance energy; they have a great difference between the electronic energy of an actual molecule and a hypothetical structure with localized bonds. Naphthalene has many pi electrons (10), which gives it the characteristic resonance of an aromatic compound. Aromatic compounds also undergo substitution rather than addition reactions because they are so stable. Therefore, all statements are associated with naphthalene's aromaticity.
