Introduction
Naphthalene is a bicyclic aromatic hydrocarbon with the formula C10H8. It is composed of two fused benzene rings and is commonly used as a moth repellent. This compound is considered aromatic due to its planar, cyclic, and fully conjugated structure.
Huckel's Rule
Huckel's rule states that a compound is aromatic if it meets the following criteria:
- The molecule must be planar.
- The molecule must be cyclic.
- The molecule must be fully conjugated, meaning that every atom in the ring must have a p orbital that participates in pi electron delocalization.
- The molecule must contain 4n + 2 pi electrons, where n is a non-negative integer.
Naphthalene and Huckel's Rule
Naphthalene satisfies all of the criteria for aromaticity according to Huckel's rule:
- Naphthalene is planar, with all of its atoms lying in the same plane.
- Naphthalene is cyclic, consisting of two fused benzene rings.
- Naphthalene is fully conjugated, with every atom in the ring having a p orbital that participates in pi electron delocalization.
- Naphthalene has 10 pi electrons, which satisfies the 4n + 2 pi electron rule when n = 2.
Conclusion
In conclusion, naphthalene is an aromatic compound according to Huckel's rule. Its planar, cyclic, and fully conjugated structure, along with its 10 pi electrons, make it a prime example of an aromatic compound.

Huckel's rule is 4n+2=π electronsif n is a whole number then the compound will be aromatic.in Naphthalene the number of π electrons is 10 hence by huckel's rule n will be 2. Hence Naphthalene is aromatic.
