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.
Chloroform is useful for us because :
- A It can be used as a solvent for oil, fats, waxes and organic compounds and also for preserving biological specimens
- B Fat, waxes and organic compounds are not soluble in it.
- C It is useful to destroy the biological specimens.
- D It releases phosgene gas after reaction with carbon dioxide, which is important for aquatic life.
Answer & Solution
Correct Answer
(A) It can be used as a solvent for oil, fats, waxes and organic compounds and also for preserving biological specimens
Step-by-step Solution
