\(\text { Benzene + ozone (excess) } \stackrel{\mathrm{CCl}_4}{\longrightarrow}\) \(\text {Benzene triozonide}\) \(\stackrel{\mathrm{Zn}/\mathrm{H}_2 \mathrm{O}}{\longrightarrow} \mathrm{P}+\mathrm{H}_2 \mathrm{O}_2\)

  1. A Benzoic acid
  2. B Benzaldehyde
  3. C Phenol
  4. D Glyoxal
Verified Solution

Answer & Solution

Correct Answer

(D) Glyoxal

Step-by-step Solution

Detailed explanation

When benzene is treated with ozone in presence of an inert solvent such as carbon tetrachloride, benzene triozonide is formed which is then decomposed by zinc dust and water to give glyoxal.
