What are chlorinated and fluorinated hydrocarbons?
Hydrocarbons containing chlorine atoms are called chlorinated hydrocarbons. Hydrocarbons containing fluorine atoms are called fluorinated hydrocarbons. eg> CHCl3, CHF3 etc
Are chlorinated hydrocarbons found in solvents?
Yes, chlorinated hydrocarbons are commonly found in solvents. They are often used as cleaning agents, degreasers, and in manufacturing processes. However, they have been associated with health and environmental concerns due to their toxicity and persistence in the environment.
Who first proposed a correlation between chlorinated hydrocarbons and ozone depletion?
The correlation between chlorinated hydrocarbons and ozone depletion was first proposed by chemists Rowland and Molina in a paper published in 1974. They showed that chlorofluorocarbons (CFCs) released into the atmosphere could reach the stratosphere where they catalyze the breakdown of ozone molecules.
Why is chlorinated hydrocarbons an environmental threat even through their use has been banned in the US?
Chlorinated hydrocarbons remain an environmental threat due to their persistence in the environment and bioaccumulation in the food chain, despite being banned in the U.S. These compounds can linger in soil and water for decades, leading to long-term contamination of ecosystems. Additionally, their toxic effects on wildlife and humans, including potential carcinogenicity and endocrine disruption, continue to pose significant health risks, impacting biodiversity and ecosystem health. As a result, even after their ban, the legacy of chlorinated hydrocarbons continues to affect both environmental and public health.
Is organic solvent an oxidizing agent?
Organic solvent can be an oxidizing agent in some circumstances but usually is not. All hydrocarbon solvents, chlorinated hydrocarbons and ethers are not for example.

Which pollution is caused by paint industry?
Heavy metals, xylene, other BTEX, Pesticides, Chlorinated Hydrocarbons

What is it call when a substance that dissolve in water?
It is said to be water soluble. Other materials may be soluble in oils, aromatic hydrocarbons, or chlorinated compounds.

What chemicals are used in insecticides?
Two common are shared by most insecticide chemicals. They are chlorinated hydrocarbons and organophosphates. Newer chemicals include parathion and malathion.

Can ozone reform?
Yes, the formation and destruction of ozone is an equilibrium reaction in the stratosphere.The formation and destruction of ozone is an ongoing process between oxygen and ultraviolet light in the stratosphere. Problems with the ozone layer developed when chlorine from chlorinated hydrocarbons (freon and CGS, etc) moved the equilibrium point in the ozone formation/destruction cycle towards a state of less ozone.Efforts to reduce the use and release of chlorinated hydrocarbons has receded the chlorinated hydrocarbons in the atmosphere and returned to ozone levels to a more normal equilibrium point.
What has the author Young Kim written?
Young Kim has written: 'Aerobic cometabolism of chlorinated aliphatic hydrocarbons by a butane-grown mixed culture' -- subject(s): Metabolism, Chlorohydrocarbons, Aliphatic compounds
What does chlorine and carbon mixed together make?
Chlorine and carbon "mixed together" simply make a mixture, but chlorine and carbon reacted with each other make a class of compounds called "chlorocarbons", of which carbon tetrachloride is the member with the smallest molecules.
