Which one of the following is likely to give a precipitate with AgNO3s...
Precipitation Reaction
A precipitation reaction is a chemical reaction that produces a precipitate, which is an insoluble solid that forms from the reaction of two soluble compounds.
AgNO3 Solution
AgNO3 is a soluble salt that dissociates to give Ag+ and NO3- ions in an aqueous solution.
Likely Precipitate
A compound is likely to give a precipitate with AgNO3 solution if it contains Cl- ions, as AgCl is insoluble in water and will form a white precipitate.
Analysis of Options
a) CHCl3
CHCl3 does not contain Cl- ions and will not give a precipitate with AgNO3 solution.
b) (CH3)3CCl
(CH3)3CCl contains Cl- ions and will give a precipitate with AgNO3 solution.
c) CH2=CH-Cl
CH2=CH-Cl does not contain Cl- ions and will not give a precipitate with AgNO3 solution.
d) CCl4
CCl4 does not contain Cl- ions and will not give a precipitate with AgNO3 solution.
Conclusion
Out of the given options, only (CH3)3CCl contains Cl- ions and will give a precipitate with AgNO3 solution, making option 'B' the correct answer.
Which one of the following is likely to give a precipitate with AgNO3s...
Tert-butyl chloride forms most stable 3° carbocation. So will give white precipitate of AgCl with AgNO3 solution immediately.
Hence, option (B) is the answer.
