How can we prepare phenol from cumene?
Options
- ABy dehydration of cumene using concentrated sulphuric acid.
- BBy reduction of cumene using hydrogen gas.
- CBy treating cumene with hydrochloric acid.
- DTo prepare phenol, cumene is first oxidized in the presence of air of cumene hydro-peroxide at 368 to 408 K. T
Correct answer
D. To prepare phenol, cumene is first oxidized in the presence of air of cumene hydro-peroxide at 368 to 408 K. T
Step-by-step solution
Correct Option is : (D) To prepare phenol, cumene is first oxidized in the presence of air of cumene hydro-peroxide at 368 to 408 K. Then, cumene hydroxide is treated with dilute acid to prepare phenol and acetone as by-products at 323 to 363 K.
