Question

Match List-I with List-II.

List-I (Test)	List-II (Identification)
(A) Bayer's test	(I) Phenol
(B) Ceric ammonium nitrate test	(II) Aldehyde
(C) Phthalein dye test	(III) Alcoholic-OH group
(D) Schiff's test	(IV) Unsaturation

Choose the correct answer from the options given below:

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

Answer 1

The Correct Option is D

To resolve the matching of chemical tests to their respective identifications, an understanding of each test's function is requisite:

1. Bayer's Test: Detects unsaturation (double or triple bonds) in organic compounds. Potassium permanganate decolorizes in the presence of unsaturation. Thus, Bayer's test is linked to unsaturation. Match: (A)-(IV).
2. Ceric Ammonium Nitrate Test: Identifies alcohols. Alcohols cause a color change in the ceric ammonium nitrate reagent. Consequently, this test is for alcohol identification. Match: (B)-(III).
3. Phthalein Dye Test: Detects the phenolic group in compounds. This is a characteristic test for phenols, which possess a phenolic -OH group. Therefore, this test correlates with phenols. Match: (C)-(I).
4. Schiff's Test: Identifies aldehydes. Schiff's reagent decolorizes and produces a magenta or purple color upon reaction with an aldehyde. Hence, Schiff's test corresponds to aldehydes. Match: (D)-(II).

The deduced correct matching is: (A)-(IV), (B)-(III), (C)-(I), (D)-(II).
