Question

Why is benzene more aromatic than naphthalene and anthracene?

Answer 1

Answer:

However, for polycyclic aromatic hydrocarbons, stability can be said to be proportional to resonance energy per benzene rings. Here resonance energy per benzene ring decreases from 36 Kcal/mol for benzene to 30.5 Kcal/mol for naphthalene, 30.3 Kcal/mol for phenanthene and 28Kcal/mol for anthracene.

Answer 2

Answer:

Here resonance energy per benzene ring decreases from 36 Kcal/mol for benzene to 30.5 Kcal/mol for naphthalene, 30.3 Kcal/mol for phenanthene and 28Kcal/mol for anthracene.

Order of stability (or RE): Benzene > Phenanthrene ~ Naphthalene > Anthracene. In fact other fused polycyclic aromatic hydrocarbons react faster than benzene.
