The Correct Option is B

Solution and Explanation

Isopropylbenzene (cumene) is oxidized in the presence of air to form cumene hydroperoxide (X).

On acidic hydrolysis, cumene hydroperoxide breaks down to give:

  • Phenol (Y)
  • Acetone (Z)

This reaction is important in industry for the commercial production of phenol and acetone.

Therefore:

X = Cumene hydroperoxide
Y = Phenol
Z = Acetone

Correct Answer:

Correct Answer: (B) cumene hydroperoxide, phenol, acetone
