What is the Difference Between Naphthalene and Camphor?

Naphthalene and camphor are two different substances that share a similar appearance, but they have distinct properties and uses. The main differences between them include:

1. Structure: Naphthalene has a molecular formula of C10H8 and consists of two fused benzene rings in its structure, while camphor has a molecular formula of C10H16O and possesses a ketone functional group in its structure.
2. Physical Properties: Naphthalene is a white crystalline solid, whereas camphor is a white transparent waxy crystalline isoprenoid ketone.
3. Toxicity: Naphthalene is considered a toxic substance, while camphor is nontoxic.
4. Production: Naphthalene is obtained from coal tar or synthesized from crude oil, while camphor is obtained from the wood of the camphor tree.
5. Uses: Camphor has various applications, including aromatherapy, respiratory disease management, pain relief, and prevention of low blood pressure and osteoarthritis. It is also used in the manufacture of plastics and explosives and as a cleaning agent and fumigant. In contrast, naphthalene is used as a moth repellent and in the production of dyes, resins, and other organic compounds, as well as for industrial applications such as plasticizers and polyester resins.

It is essential to differentiate between naphthalene and camphor due to their varying toxicities and applications. Misinterpreting these two substances can lead to potential health risks or incorrect usage.

Comparative Table: Naphthalene vs Camphor

Here is a table comparing the differences between naphthalene and camphor:

Naphthalene and camphor are both organic compounds with similar appearances but different chemical structures. Naphthalene is a polycyclic aromatic hydrocarbon with two fused benzene rings, while camphor is a terpenoid with a ketone functional group in its structure. The key difference between the two is that naphthalene is toxic to humans, whereas camphor is not.
