In 1865 as a direct result of the criminal reputation chloroform had gained, the medical journal The Lancet offered a "permanent scientific reputation" to anyone who could demonstrate "instantaneous insensibility", i.e. chloroform (CHCl3), also called trichloromethane, nonflammable, clear, colourless liquid that is denser than water and has a pleasant etherlike odour. This is why chloroform is considered too dangerous to be used as an anesthetic. It destroys bacteria, viruses, and pests by chlorination. It is a trihalomethane that serves as a powerful anesthetic, euphoriant, anxiolytic, and sedative when inhaled or ingested.

We do not know whether liver and kidney cancer would develop in people after long-term exposure to chloroform in drinking water. [14], As chloroform is a volatile organic compound,[15] it dissipates readily from soil and surface water and undergoes degradation in air to produce phosgene, dichloromethane, formyl chloride, carbon monoxide, carbon dioxide, and hydrogen chloride. It can harm the eyes, skin, liver, kidneys, and nervous system. [11], The total global flux of chloroform through the environment is approximately 660000 tonnes per year,[12] and about 90% of emissions are natural in origin. [8] At 400500C, a free radical halogenation occurs, converting these precursors to progressively more chlorinated compounds: Chloroform undergoes further chlorination to yield carbon tetrachloride (CCl4): The output of this process is a mixture of the four chloromethanes: chloromethane, dichloromethane, trichloromethane (chloroform), and tetrachloromethane (carbon tetrachloride). border: #151515 0px solid; [33], The hydrogen attached to carbon in chloroform participates in hydrogen bonding. WebChloroform is a clear, colourless, volatile liquid with a characteristic sweet odour. It is also a precursor to various refrigerants.
