Question

Match List - I (Name of the reaction) with List - II (Conversion):

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

Hint:

Reimer-Tiemann adds an aldehyde (-CHO); Kolbe adds an acid (-COOH). Simple!

Answer 1

The Correct Option is B

Step 1: Concept This question involves matching common organic name reactions to their typical synthetic utility.

Step 2: Meaning Each named reaction is a hallmark tool for specific aromatic or functional group constructions.

Step 3: Analysis (A) The thermal cyclization of ortho-methyl diaryl ketones to form polycyclic aromatic hydrocarbons is the Elbs reaction (II - Synthesis of Anthracene). (B) The formulation of phenols using $CHCl_{3}$ and NaOH is the Reimer-Tiemann reaction (IV - Synthesis of Salicylaldehyde). (C) The carboxylation of sodium phenoxide to form hydroxy-acids is the Kolbe-Schmitt reaction (I - Synthesis of salicylic acid). (D) The thermal rearrangement of allyl phenyl ethers to ortho-allyl phenols is the Claisen rearrangement (III).

Step 4: Conclusion The matching sequence is A-II, B-IV, C-I, D-III. Final Answer: (B)
