Match List-I with List-II. List-I (Compound) List-II (Identification Test) (A) Phenol (I) Iodoform test (B) Ethanol (II) Neutral FeCl ₃ test (C) Acetaldehyde (III) NaHCO ₃ test (D) Acetic acid (IV) Tollen's reagent Choose the correct answer from the options given below:
Options
- A(A)-(II), (B)-(I), (C)-(IV), (D)-(III)
- B(A)-(I), (B)-(II), (C)-(IV), (D)-(III)
- C(A)-(II), (B)-(I), (C)-(III), (D)-(IV)
- D(A)-(II), (B)-(IV), (C)-(I), (D)-(III)
Correct answer
A. (A)-(II), (B)-(I), (C)-(IV), (D)-(III)
Step-by-step solution
Phenol gives a characteristic violet colour with neutral FeCl ₃ solution. Ethanol contains the CH ₃ CH(OH) - group and hence gives a positive iodoform test, forming a yellow precipitate of CHI ₃ . Acetaldehyde is an aldehyde and gives a positive Tollen's test, forming a silver mirror. Acetic acid is a carboxylic acid and reacts with NaHCO ₃ to give effervescence of CO ₂ gas. Therefore, the correct matching is (A)-(II), (B)-(I), (C)-(IV), (D)-(III). Answer: (A)-(II), (B)-(I), (C)-(IV), (D)-(III)
