Chemistry - AMINES Question with Solution | TestHub

Question Explanation:

The question asks to identify which of the provided reagents, when reacted with aniline will produce a water-insoluble product.

Concept: This question is based on

1. Diazotization. 

2. Balz-Schiemann Reaction.

3. Oxidation of Aniline.

4. Solubility of Organic Compounds.

Solution:  

Aniline reacts with NaNO₂ + HBF₄ (diazotization followed by Balz-Schiemann) to form benzene diazonium fluoroborate (C₆H₅N₂ + BF₄^- ), which is water-insoluble and stable at room temperature.

Aniline with NaNO₂ + HCl (diazotization) yields benzene diazonium chloride (C₆H₅N₂ + Cl^- ), which is water-soluble and unstable above 0-5°C.

Strong oxidants like acidified K₂Cr₂O₇ convert aniline to primarily water-insoluble p-benzoquinone. Trifluoroperacetic acid (CF₃CO₃H) oxidizes aniline to water-insoluble nitrobenzene (C₆H₅NO₂ ). Therefore, reagents (A), (C), and (D) produce water-insoluble products.

Final Answer:  Options (A), (C), and (D).
