JEE Main Chemistry Question (2026) — Solution
Question
Match List - I with List - II. array l List - I & List - II \\ Functional group (detection) & Change observed during detection \\ A. Unsaturation (Baeyer's test) & I. Red colour appears \\ B. Alcoholic group \\ (Ceric ammonium nitrate test) & II. Silver mirror appears \\ C. Aldehyde group (Tollen's reagent) & III. Violet colour appears \\ D. Phenolic group ( FeCl _ 3 . test) & IV. Discharge of pink colour array Choose the correct answer from the options given below :
Options
- A. A-III, B-IV, C-II, D-I
- B. A-IV, B-I, C-II, D-III
- C. A-IV, B-III, C-II, D-I
- D. A-III, B-IV, C-I, D-II
Answer
B. A-IV, B-I, C-II, D-III
Step-by-step solution
Unsaturation (Baeyer's test) involves decolorization of the reagent, represented by discharge of color (IV). Alcoholic groups (Ceric ammonium nitrate test) produce a red color (I). Aldehyde groups (Tollen's reagent) produce a characteristic silver mirror effect (II). Phenolic groups (FeCl₃ test) produce a violet or pink color (III). The correct matching is A-IV, B-I, C-II, D-III.
