Question

Isopropylbenzene (cumene) is oxidized in the presence of air to give compound 'X which on hydrolysis in the presence of acids gives compounds 'Y' and 'Z. Compounds 'X', 'Y' and 'Z' are respectively

• A. benzyl alcohol, benzaldehyde, ethanol
• B. cumene hydroperoxide, phenol, acetone
• C. cumene hydroperoxide, benzaldehyde, acetone
• D. cumene hydroperoxide, phenol, acetaldehyde
• E. cumerc hydroperoxide, benzaldehyde, acetaldehyde

Answer 1

The Correct Option is B

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
