Reaction of compounds with AgNO3
- AgNO3 is a silver salt that is commonly used as a reagent to test for the presence of halides in organic compounds.
- When AgNO3 is added to a halide-containing organic compound, a white precipitate of AgX is formed, where X is the halide (Cl, Br, or I).
- The rate of this reaction depends on the reactivity of the halide, with more reactive halides forming precipitates faster.
Comparison of compounds
- The three compounds given are (CH3)3CCI, (CH3)2CHCH2CI, and (CH3)2CHCI.
- All three compounds contain a halide (Cl) that can react with AgNO3 to form a precipitate.
- (CH3)3CCI has three methyl groups attached to the carbon with the Cl, making it more bulky and less reactive than the other two compounds.
- (CH3)2CHCI has two methyl groups attached to the carbon with the Cl, and (CH3)2CHCH2CI has one methyl group and a longer chain attached to the carbon with the Cl.
- Therefore, (CH3)2CHCI is expected to be more reactive than (CH3)3CCI, but less reactive than (CH3)2CHCH2CI.
Conclusion
- The correct answer is option A, (CH3)3CCI, which is the least reactive of the three compounds due to its bulkiness.
- This is because the reaction rate of the compounds with AgNO3 depends on the reactivity of the halide, and the more bulky compound is expected to be less reactive.
