Tetrachlormethane, also known as carbon tetrachloride, is a colorless liquid with a sweet odor. The word is spelled as "tet-ra-klor-meth-ane" in IPA phonetic transcription. The "tetra" prefix means "four," highlighting that this chemical compound contains four chlorine atoms. The "ane" suffix denotes that it is an alkane, a class of organic compounds that consists of hydrogen and carbon atoms only. Tetrachlormethane was commonly used as a solvent and refrigerant, but its production and use have been phased out due to environmental concerns.
Tetrachloromethane, also known as carbon tetrachloride, is a colorless, heavy, nonflammable liquid with the chemical formula CCl4. It is composed of one carbon atom bonded to four chlorine atoms.
Tetrachloromethane is primarily used as a solvent for oils, fats, lacquers, and resins due to its high solubility and low toxicity. It has a sweet odor and is relatively stable in normal conditions. However, it can decompose at high temperatures, releasing toxic and corrosive fumes such as phosgene gas.
In the past, tetrachloromethane was used as a fire extinguishing agent because it does not conduct electricity and evaporates rapidly, thereby minimizing damage caused by water. However, its use as a fire suppressant has declined due to its harmful effects on the ozone layer. Exposure to tetrachloromethane can occur through inhalation, ingestion, or direct contact with the skin. It can have harmful effects on the liver, kidneys, and central nervous system, causing symptoms such as headaches, dizziness, and nausea.
Due to its toxicity and environmental impact, the production and use of tetrachloromethane have been restricted or banned in many countries. It is classified as a hazardous substance and requires proper handling, storage, and disposal. Ongoing research is focused on the development of safer alternatives to tetrachloromethane to minimize its negative impacts on human health and the environment.

The word tetrachlormethane has a Greek and Latin etymology.
The Greek root tetra- means four, indicating that there are four chlorine atoms in the compound.
The Latin component chlor comes from the Latin word chlorum, which means green or chlorine.
The suffix -methane refers to a type of hydrocarbon compound, which is composed of carbon atoms bonded to hydrogen atoms.
Therefore, when combined, the term tetrachlormethane literally means a compound with four chlorine atoms attached to a methane-like structure.
