Which of the following is an example of a chlorinated hydrocarbon pesticide?

Chlordane is classified as a chlorinated hydrocarbon pesticide, which is a group of synthetic organic compounds that contain chlorine atoms. These pesticides are known for their effectiveness at controlling a wide range of pests and were commonly used in agriculture and for termite control. Chlordane, in particular, was widely used until it was banned in the United States due to concerns over environmental and health impacts.

Chlorinated hydrocarbons derive their name from their chemical structure, which includes carbon, hydrogen, and chlorine atoms. Their persistence in the environment and bioaccumulation in the food chain are characteristics of many in this group, making them effective yet controversial.

The other options listed, such as glyphosate, permethrin, and imidacloprid, belong to different chemical classes. Glyphosate is a glyphosate-based herbicide, permethrin is a synthetic pyrethroid (a type of insecticide that mimics natural pyrethrins), and imidacloprid is a neonicotinoid, which acts on the nervous system of insects. Each of these has a different mode of action and chemical structure, distinguishing them from chlorinated hydrocarbons like chlordane.
