DDT should not be allowed to come in contact with iron (during its manufacture) to _______________?
Correct answer: A. Avoid its decomposition
- A. Avoid its decomposition
- B. Prevent sulphonation of the monochlorobenzene by the acid catalyst
- C. Achieve non-hygroscopic property
- D. None of these
Explanation
Iron must be excluded because it promotes decomposition of DDT during manufacture, reducing product quality. The reaction is not intended to sulphonate monochlorobenzene, so option b does not describe the main reason.
