Question

Match List I with List II

List-I (Reaction)		List-II  (Reagents/Condition)
(A)		(I)
(B)		(II)	CrO3
(C)		(III)	KMnO4/KOH, \(\Delta\)
(D)		(IV)	(i) O3 (ii) Zn-H2O

Choose the correct answer from the options given below:

• A. A-IV, B-I, C-III, D-II
• B. A-III, B-I, C-II, D-IV
• C. A-IV, B-I, C-II, D-III
• D. A-I, B-IV, C-II, D-III

Answer 1

The Correct Option is C

This section requires matching reactions from List-I with the appropriate reagents/conditions from List-II.

(A) Cyclohexene to Cyclohexanone:
This conversion is achieved via ozonolysis followed by reductive workup using $ \text{Zn} $ and $ \text{H}_2\text{O} $. Reagent (IV) ($ \text{O}_3 $ followed by $ \text{Zn}-\text{H}_2\text{O} $) is suitable for this oxidation.
(A) matches (IV).

(B) Benzene to Benzophenone:
This is a Friedel-Crafts acylation. It requires an acyl halide (e.g., benzoyl chloride) and a Lewis acid catalyst (e.g., anhydrous $ \text{AlCl}_3 $). Reagent (I) corresponds to these conditions.
(B) matches (I).

(C) Cyclohexanol to Cyclohexanone:
This is the oxidation of a secondary alcohol to a ketone, typically using $ \text{CrO}_3 $. Reagent (II) is appropriate.
(C) matches (II).

(D) Ethylbenzene to Potassium Benzoate:
Oxidation of the alkyl side chain of ethylbenzene to a carboxylate salt is achieved with strong oxidizing agents like alkaline potassium permanganate ($ \text{KMnO}_4/\text{KOH} $) under heating ($ \Delta $). Reagent (III) fits this reaction.
(D) matches (III).

Summary of Matches:
(A) - (IV)
(B) - (I)
(C) - (II)
(D) - (III)

Final Answer:
The pairings are: $ \boxed{\text{A-IV, B-I, C-II, D-III}} $
