Question

Match List-I with List-II:

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

Answer 1

The Correct Option is A

This matching exercise requires knowledge of organic chemistry reagents and their applications. The correct pairings are detailed below:

• A - Lucas Reagent: This reagent, a solution of anhydrous zinc chloride in concentrated hydrochloric acid, differentiates alcohols based on their reactivity. Tertiary alcohols react instantaneously, causing cloudiness. Consequently, A corresponds to III.
• B - Carbylamine Reaction: This test is specific for primary amines, producing a foul-smelling isocyanide. Thus, B is matched with IV.
• C - Iodoform Test: This test identifies methyl ketones and certain alcohol groups (e.g., ethanol) by forming a yellow precipitate of iodoform. Therefore, C matches II.
• D - Tollens' Test: Used to detect aldehydes, Tollens' reagent yields a silver mirror on the inner walls of the test tube. Hence, D is paired with I.

The finalized matching is: A-III, B-IV, C-II, D-I.
