Question

Match the list-I with list-II 

• A. (I)-(Q), (II)-(S), (III)-(R), (IV)-(R)
• B. (I)-(P), (II)-(S), (III)-(R), (IV)-(R)
• C. (I)-(Q), (II)-(S), (III)-(P), (IV)-(R)
• D. (I)-(P), (II)-(S), (III)-(P), (IV)-(S)

Answer 1

The Correct Option is B

Step 1: Understanding the reagents and their uses. 
We need to match the reagents from List-I with the corresponding chemical reactions or reagents used in List-II. Let's analyze each reagent and its application: 

Step 2: Reagent analysis. 
- (I) Tollen's reagent: Tollen's reagent is used for the detection of aldehydes, particularly in the silver mirror test. It contains \(\text{Cu}^{2+}\) and \(\text{OH}^-\) ions. Hence, it matches with \((P)\).
- (II) Fehling's reagent: Fehling's reagent is used to test for the presence of reducing sugars and aldehydes, where it reacts with \([Ag(NH_3)_2]^+\) and \(\text{OH}^-\) ions. It corresponds with \((S)\).
- (III) Williamson method: The Williamson ether synthesis method uses an alkoxide (\(RO^-\)) reacting with alkyl halides (R-X) to form ethers, which corresponds with \((R)\).
- (IV) Bayer's reagent: Bayer's reagent is used for the oxidation of alkenes to diols using diluted potassium permanganate (\(KMnO_4\)), hence it corresponds with \((R)\).

Step 3: Conclusion. 
The correct matching is (B) because each reagent corresponds with the correct chemical reagent or reaction as described. (B) (I)-(P), (II)-(S), (III)-(R), (IV)-(R).
