Benzene is converted to benzene sulfonate using sulphuric acid and eventually through the benzene sulfonate is gradually transformed to phenol
- A. neutralization
- B. fusion
- C. acidification
- D. All of the above
Step-by-step solution
The conversion of benzene to phenol via sulfonation involves multiple steps: sulfonation to benzenesulfonic acid, neutralization to sodium benzenesulfonate, fusion with NaOH to yield sodium phenoxide, and finally acidification to phenol. The key step that transforms the benzene sulfonate (sodium benzenesulfonate) directly into phenoxide is alkali fusion, making 'fusion' the correct answer.
