    Carbon tetrachloride (CCl₄) was historically used as a cleaning agent and solvent due to its low flammability. It found applications in dry cleaning, metal degreasing, and spot cleaning fabrics. However, its use diminished due to environmental and health concerns. Carbon tetrachloride is a known carcinogen and poses risks of liver and kidney damage upon exposure. Today, its major applications include its use as a feedstock in the production of chemicals like refrigerants and the synthesis of various organic compounds. Strict regulations govern its industrial use to minimize environmental and health risks associated with its handling.

    Exposure to carbon tetrachloride (CCl₄) poses serious health risks. Inhalation can cause respiratory irritation, nausea, and headaches. Chronic exposure may lead to liver and kidney damage, and it is classified as a known human carcinogen. Carbon tetrachloride readily penetrates the central nervous system, causing neurological effects such as dizziness, confusion, and incoordination. Additionally, it can affect the heart, leading to cardiac arrhythmias and other cardiovascular issues. Due to these severe health concerns, occupational exposure to carbon tetrachloride is strictly regulated, and measures are taken to minimize contact and protect individuals from its detrimental effects.

    The release of carbon tetrachloride (CCl₄) into the air contributes to environmental concerns, particularly regarding the ozone layer. Although CCl₄ itself is not a significant ozone-depleting substance, it can break down in the upper atmosphere, releasing chlorine atoms. These chlorine atoms participate in catalytic reactions that lead to ozone depletion. The destruction of ozone molecules in the stratosphere allows more harmful ultraviolet (UV) radiation to reach the Earth’s surface, posing risks to human health and ecosystems. Strict regulations are in place to control and minimize the release of carbon tetrachloride to mitigate its impact on the ozone layer.

    Freons are a group of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) that were commonly used as refrigerants and aerosol propellants. Their suitability for industrial use arises from several characteristics. Freons are non-toxic, non-flammable, and chemically inert, making them safe for various applications. They have low boiling points, allowing them to absorb and release heat efficiently in refrigeration systems. However, their use has been phased out due to their role in ozone depletion, as chlorine atoms released from freons in the atmosphere contribute to the breakdown of ozone molecules in the stratosphere, leading to the development of more environmentally friendly alternatives.

    Freon-12, also known as dichlorodifluoromethane (CFC-12), was historically manufactured by reacting carbon tetrachloride with hydrogen fluoride. However, due to environmental concerns, its production has been largely phased out. Freons, including Freon-12, were commonly used in industrial applications as refrigerants in air conditioning and refrigeration systems. Their low boiling points and heat-absorbing properties made them effective in heat transfer. They were also used as propellants in aerosol products. In modern times, the use of Freon-12 has decreased significantly due to its ozone-depleting potential, and alternative, environmentally friendly refrigerants have been adopted in many applications.
