Question

Match List-I with List-II. 

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

Hint:

Tollen's test is the easiest to remember: Aldehydes make mirrors!

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Functional groups are identified by specific chemical tests that produce characteristic color changes or precipitates.
Step 2: Detailed Explanation:
- A. Unsaturation (Baeyer's test): Cold alkaline $KMnO_4$ is pink. Reaction with alkenes decolourises it. $\rightarrow$ IV. - B. Alcoholic group (CAN test): Ceric ammonium nitrate forms a red complex with alcohols. $\rightarrow$ I. - C. Aldehyde group (Tollen's): Aldehydes reduce $Ag^+$ to metallic silver. $\rightarrow$ II. - D. Phenolic group ($FeCl_3$): Neutral ferric chloride forms a violet complex with phenols. $\rightarrow$ III.
Step 3: Final Answer:
The matching is A-IV, B-I, C-II, D-III.
