Chlorinated hydrocarbons consist of simple hydrocarbons in which one or more hydrogen atoms have been replaced with chlorine.
An organochloride, organochlorine, or chlorocarbon, is an organic compound containing at least one covalently bonded chlorine atom. Their wide structural variety and divergent chemical properties lead to a broad range of uses.
Chlorophyll is a green pigment found in most plants, algae, and cyanobacteria. Chlorophyll absorbs light most strongly in the blue and red but poorly in the green portions of the electromagnetic spectrum, hence the green color of chlorophyll-containing tissues like plant leaves.
