Naphthalene Balls:Naphthalene balls, commonly known as mothballs, are small, white, or translucent balls composed primarily of naphthalene or paradichlorobenzene. These balls are solid hydrocarbons that are widely used as a household product, primarily for their insect-repellent and deodorizing properties.Key Characteristics:Chemical Composition:Traditional naphthalene balls are made from naphthalene (C??H?), a white crystalline substance derived from coal tar or petroleum.Some modern versions use paradichlorobenzene (C?H?Cl?) as a safer alternative.Appearance:Small, spherical or oval, white in color.Solid and slightly waxy to the touch.Odor:Strong, distinct, and pungent smell.The odor arises due to the sublimation of naphthalene, turning directly from a solid to a gas.Uses:Insect Repellent:Commonly used to protect clothes from moths, larvae, and other insects when stored in cupboards or closets.Effective in repelling cockroaches and other pests as well.Deodorizer:Used in toilets, bathrooms, and other areas to mask unpleasant odors.Industrial Applications:Occasionally used in industrial settings for their chemical properties in organic synthesis.Advantages:Affordable and widely available.Long-lasting due to slow sublimation.Effective against a variety of pests.Health and Safety Concerns:Toxicity:Both naphthalene and paradichlorobenzene are toxic and can cause health issues if inhaled or ingested.Prolonged exposure may lead to respiratory issues, headaches, or dizziness.Particularly harmful to children and pets if consumed.Environmental Impact:Naphthalene is flammable and can be a pollutant if not disposed of properly.
