Slow oxidation of chloroform in air leads to
WebbChloroform was withdrawn from clinical use because it can cause nervous system depression, anoxia secondary to respiratory depression and airway obstruction, cardiac dysrhythmias potentiated by circulating catecholamines, and hepatotoxicity, which is thought to be secondary to oxidative injury caused by free radicals. WebbChloroform: It is a colorless liquid that evaporates easily into gas. It is an inorganic compound having molecular formula as CHCl 3. Reaction of Chloroform with air and sunlight: When Chloroform CHCl 3 reacts with air and sunlight, it produces a toxic gas known as Phosgene gas COCl 2 along with Hydrochloric acid HCl.

WebbIt gets dissolved in the air where oxygen is present and it slowly reacts with chloroform. The reaction of oxygen and chloroform forms a toxic gas called phosgene. This gas is indeed more toxic and harmful than chloroform itself. It adversely affects our environment by harming its properties. Webb14 jan. 2024 · The correct option is (b) Both A and R are true but R is not correct explanation of A.. Explanation: Chloroform is slowly oxidised by air in the presence of light to an extremely poisonous gas 'phosgene'. Therefore, it is stored in dark bottles, completely filled so that air is kept out.
Webb1 juni 1993 · The complete catalytic oxidation of chloroform over a 2% platinum [alpha]-alumina catalyst was investigated using a fixed bed catalytic reactor operated at temperatures between 300 and 400 [degree]C and concentrations between 100 and 5,000 ppm (v/v) in humid air at atmospheric pressure.
