Options

  1. AA-III, B-IV, C-II, D-I
  2. BA-IV, B-I, C-II, D-III
  3. CA-IV, B-III, C-II, D-I
  4. DA-III, B-IV, C-I, D-II

Correct 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.
