What substance class do inorganic pesticides belong to?

1. Organic compounds

2. Mineral origin substances

3. Synthetic chemicals

4. Biological products

The correct answer is: Mineral origin substances

Inorganic pesticides are classified as mineral origin substances because they are derived from non-carbon based minerals or elements found in nature. These substances do not contain carbon-hydrogen bonds, which distinguishes them from organic compounds that typically consist of carbon and are derived from living organisms or their byproducts. Inorganic pesticides often include elements such as sulfur, copper, and arsenic, which can be effective in pest control due to their properties. The classification of inorganic pesticides as mineral origin substances highlights their source and composition, emphasizing their natural occurrence in the earth's crust rather than any synthetic process. This classification is important for understanding the chemical nature of these pesticides and their potential environmental impacts compared to other classes of pesticides, such as organic compounds or synthetic chemicals.
