What property of paradichlorobenzene may convince you that it is an ingredient in mothballs?

The odor.

To determine if paradichlorobenzene is an ingredient in mothballs, you can look at its properties. Here's how you can find the information:

1. Conduct an online search: Begin by using search engines like Google or Bing to look for the properties of paradichlorobenzene. Enter keywords such as "properties of paradichlorobenzene."

2. Explore reliable sources: Focus on reputable sources such as scientific databases and websites of government agencies or educational institutions. Examples include chemistry-related websites, material safety data sheets (MSDS), or academic journals.

3. Analyze the properties: Look for specific properties of paradichlorobenzene that relate to its use in mothballs, such as its odor, volatility, solubility, and toxicity.

Key property of paradichlorobenzene commonly associated with mothballs:

1. Odor: Paradichlorobenzene has a strong, distinctive odor that is commonly associated with mothballs. This odor helps repel moths and other pests.

Other properties of paradichlorobenzene:

1. Volatility: Paradichlorobenzene is a volatile compound, meaning it easily vaporizes at room temperature. This property allows it to release fumes that repel insects over an extended period.

2. Solubility: Paradichlorobenzene is not very soluble in water but dissolves well in organic solvents, such as alcohol or ethyl acetate. This solubility property enables it to disperse throughout the fabric when used as a moth repellent.

3. Toxicity: Paradichlorobenzene is considered toxic and potentially harmful to humans and animals if ingested or inhaled in high concentrations. Due to its toxic nature, caution should be exercised when handling or using products that contain paradichlorobenzene.

By examining these properties, it can be determined that paradichlorobenzene, with its distinctive odor, volatility, solubility, and toxicity, is commonly used as an ingredient in mothballs.
