Question

Match List - I with List - II. 


Choose the correct answer from the options given below:

• A. A-IV, B-III, C-II, D-I
• B. A-III, B-II, C-I, D-IV
• C. A-III, B-I, C-II, D-IV
• D. A-III, B-IV, C-I, D-II

Hint:

Chichibabin is for Pyridines; Etard is for Toluene; Arndt-Eistert is for stretching the carbon chain!

Answer 1

The Correct Option is C

Step 1: Concept This is a matching exercise for classic named reactions in organic chemistry.

Step 2: Meaning Each conversion is a specific named transformation discovered by various chemists.

Step 3: Analysis (A) Pyridine to 2-Aminopyridine using $NaNH_{2}$ is the Chichibabin reaction (III). (B) The oxidation of ortho-hydroxy aldehydes to phenols using $H_{2}O_{2}$ in base is the Dakin reaction (I). (C) The oxidation of a methyl group on an aromatic ring to an aldehyde using chromyl chloride is the Etard reaction (II). (D) Converting a carboxylic acid to its next higher homolog is the Arndt-Eistert Synthesis (IV).

Step 4: Conclusion The correct matches are A-III, B-I, C-II, D-IV. Final Answer: (C)
