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 |
Bayer’s test: Identifies unsaturation by decolorization of potassium permanganate (KMnO$_4$).
Ceric ammonium nitrate test: Identifies alcoholic groups (–OH).
Phthalein dye test: Confirms phenol groups (C$_6$H$_5$OH).
Schiff’s test: Used for detecting aldehydes (–CHO).
Correct matching:
\[ \text{(A)-(IV), (B)-(III), (C)-(I), (D)-(II).} \]
