2024 Aldehydes, Ketones and Carboxylic AcidsOxidation, Friedel-Crafts and Ozonolysis Reactions Hard Question 9 of 91 in Aldehydes, Ketones and Carboxylic Acids

Match List-I (Reaction, shown as structures) with List-II (Reagents/Condition) for the given organic transformations.

Column I

  • A. -
  • B. -
  • C. -
  • D. -

Column II

  • I. $C_6H_5COCl$ / Anhyd. $AlCl_3$
  • II. $CrO_3$
  • III. $KMnO_4$/$KOH$, $\Delta$
  • IV. (i) $O_3$ (ii) $Zn$-$H_2O$

Correct answer: A → IV, B → I, C → II, D → III

Solution

(A) Cleavage of the C=C bond to give two molecules of cyclohexanone: (i) $O_3$ (ii) $Zn-H_2O$ – ozonolysis
(B) Benzene to benzophenone: benzoyl chloride / anhyd. $AlCl_3$ – Friedel-Crafts acylation
(C) Cyclohexanol to cyclohexanone: $CrO_3$ – mild oxidation
(D) Ethylbenzene side chain to $-COOK$: $KMnO_4$/KOH, $\Delta$ – strong oxidation
Correct match: A-IV, B-I, C-II, D-III.
