Answer the question on basis of passage given below :
Chloroform is a very useful solvent for oils, fats and waxes and many organic compounds. It can also be used for preserving biological specimens. Chloroform was used as a general anaesthetic in surgery for a long time but because of its toxic nature, it is no longer used these days.
Why storage of chloroform is a problem?
- A Chloroform gets oxidised to highly poisonous gas phosgene in the presence of oxygen
- B Chloroform gets reduced to the highly poisonous gas, phosgene.
- C Chloroform gets both oxidised followed by reduction to highly poisonous gas phosgene.
- D Chloroform gets oxidised to form chlorine and HCL
Answer & Solution
Correct Answer
(A) Chloroform gets oxidised to highly poisonous gas phosgene in the presence of oxygen
Step-by-step Solution
Detailed explanation
Chloroform (\( \text{CHCl}_3 \)) gets oxidised to highly poisonous gas phosgene (\( \text{COCl}_2 \)) in the presence of oxygen (\( \text{O}_2 \)).

The coordination compounds are of great importance. These compounds are widely present in the mineral, plants and animal world and are known to play many important functions in the area of analytical chemistry, metallurgy, biological systems, industry and medicine. For example, coordination compounds find use in many qualitative and quantitative chemical analysis. Some important metal extraction and purification make use of complex formation. Hardness of water can be estimated by stable complex formation of Ca\(^{2+}\) and Mg\(^{2+}\)
