The correct Answer is:
To solve the question "Alcoholic AgNO₃ does not give precipitate with:", we need to analyze the behavior of each compound when reacted with alcoholic silver nitrate (AgNO₃). ### Step-by-Step Solution: 1. **Understanding the Reaction**: Alcoholic silver nitrate is used to test for the presence of halides. When a halide reacts with AgNO₃, it typically forms a precipitate of silver halide (AgX). 2. **Analyzing Benzyl Chloride (C₆H₅CH₂Cl)**: - Benzyl chloride can undergo nucleophilic substitution due to the presence of the benzylic carbon. - When reacted with alcoholic AgNO₃, it forms a benzyl cation (C₆H₅CH₂⁺) and precipitates silver chloride (AgCl). - **Conclusion**: Benzyl chloride gives a precipitate. 3. **Analyzing Allyl Chloride (CH₂=CH-CH₂Cl)**: - Allyl chloride can also undergo nucleophilic substitution. - Upon reaction with alcoholic AgNO₃, it forms an allylic cation (CH₂=CH-CH₂⁺) and precipitates silver chloride (AgCl). - **Conclusion**: Allyl chloride gives a precipitate. 4. **Analyzing Chlorobenzene (C₆H₅Cl)**: - Chlorobenzene does not undergo nucleophilic substitution easily due to the stability of the aromatic ring. - When reacted with alcoholic AgNO₃, it does not form a cation and does not precipitate silver chloride. - **Conclusion**: Chlorobenzene does not give a precipitate. 5. **Analyzing Tertiary Butyl Chloride ((CH₃)₃CCl)**: - Tertiary butyl chloride can undergo nucleophilic substitution due to the stability of the tertiary cation. - When reacted with alcoholic AgNO₃, it forms a tertiary butyl cation and precipitates silver chloride (AgCl). - **Conclusion**: Tertiary butyl chloride gives a precipitate. ### Final Answer: The compound that does not give a precipitate with alcoholic AgNO₃ is **Chlorobenzene (C₆H₅Cl)**.
