Chlorinated hydrocarbons are sometimes referred to as:

Chlorinated hydrocarbons are compounds that contain both chlorine and carbon, often used in various applications including pest control due to their effectiveness as pesticides. The term "chlorinated organics" encompasses a broad range of organic compounds that include chlorine atoms in their structure. This category is appropriate because chlorinated hydrocarbons fit the definition of organic compounds while highlighting their chlorine content.

The other choices represent different classes of pesticides or organic compounds. Carbamates are a specific group of pesticides that are distinct from chlorinated hydrocarbons, as they work through a different mechanism involving carbamate functional groups. Botanicals refer to natural plant-derived compounds used as pesticides, which do not include synthetic chlorinated hydrocarbons. Lastly, natural pesticides are typically non-synthetic substances derived from natural sources, further distinguishing them from the synthetic nature of chlorinated hydrocarbons. Therefore, the designation of chlorinated hydrocarbons as chlorinated organics is accurate and reflects their chemical structure effectively.
