####2. Which one of the following is likely to give a precipitate with $AgNO _3$ solution?

(b) $CCl _4$
(d) $\left(CH _3\right) _3 CCl$

Show Answer
Solution:
- $\left(CH _3\right) _3 CCl$ gives a precipitate with $AgNO _3$ solution because it forms stable carbocation. (i.e. tertiary) that readily combines with $AgNO _3$ to give precipitates of $AgCl$.
$CH _2=CH-Cl$ forms unstable carbocation.
Hence, it does not readily react with $AgNO _3$.
