Match List - I with List - II. List - I Mixture of Compounds List - II Reagent used to distinguish A. Diethyl amine + Ethyl amine I. Bromine water B. Acetaldehyde + Acetone II. CHCl_3 + KOH, C. Ethanol + Phenol III. Neutral FeCl_3 D. Benzoic acid + Cinnamic acid IV. Ammonical silver nitrate Choose the correct answer from the options given below :
D. A-II, B-IV, C-III, D-I
Diethyl amine is a secondary amine and ethyl amine is a primary amine. Primary amines give the carbylamine test with CHCl_3 and KOH on heating, while secondary amines do not. Thus, A matches with II. Acetaldehyde is an aldehyde and acetone is a ketone. Aldehydes reduce ammoniacal silver nitrate (Tollens' reagent) to form a silver mirror, while ketones do not. Thus, B matches with IV. Phenol reacts with neutral FeCl_3 to form a violet-colored complex, whereas ethanol does not react. Thus, C matches with III. Cinnamic acid contains a carbon-carbon double bond which decolorizes bromine water, whereas benzoic acid does not react with bromine water. Thus, D matches with I. The correct matching is A-II, B-IV, C-III, D-I. Answer: A-II, B-IV, C-III, D-I
