Question

Match List I with List II.

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

Hint:

When identifying functional groups, use specific tests that target hydroxyl, carbonyl, and aldehyde groups. Each test is unique to the functional group it detects.

Answer 1

The Correct Option is A

Step 1: Analyzing ethanol (I).
Ethanol gives a positive test with Neutral FeCl₃, which confirms the presence of the hydroxyl group (\( \text{OH} \)). Step 2: Analyzing phenol (II).
Phenol gives a positive test with Cerric ammonium nitrate, indicating the presence of the hydroxyl group attached to an aromatic ring. Step 3: Analyzing ethanoic acid (III).
Ethanoic acid gives a positive test with Schiff reagent, which is characteristic of aldehydes and certain carbonyl compounds like acids. Step 4: Analyzing acetaldehyde (IV).
Acetaldehyde gives a positive test with NaHCO₃, indicating the presence of a carbonyl group (as acetaldehyde is an aldehyde). Step 5: Conclusion.
The correct matching is I-P, II-Q, III-R, IV-S, making option (1) the correct answer. Final Answer:} I-P, II-Q, III-R, IV-S.
