JEE Mains · Chemistry · STD 11 - 8.3. Organic chemistry purification and characterization
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 :
- A A-IV, B-II, C-I, D-III
- B A-IV, B-II, C-III, D-I
- C A-II, B-IV, C-I, D-III
- D A-II, B-IV, C-III, D-I
Answer & Solution
Correct Answer
(D) A-II, B-IV, C-III, D-I
Step-by-step Solution
Detailed explanation
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…
