List-II (Identification)
(I) Phenol
(II) Aldehyde
(III) Alcoholic-OH group
(IV) Unsaturation
Choose the correct answer from the options given below:
Answer: A → IV, B → III, C → I, D → II
Solution
Bayer's test (cold, dilute ) detects unsaturation (decolorises with alkenes/alkynes) — (IV).
Ceric ammonium nitrate test gives a red colour with an alcoholic group — (III).
Phthalein dye test (fusion with phthalic anhydride) is characteristic of phenols — (I).
Schiff's test (Schiff's reagent regains pink colour) is characteristic of aldehydes — (II).
Matching: (A)-(IV), (B)-(III), (C)-(I), (D)-(II).
