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. $CHCl_3 + KOH, \Delta$
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 :

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
