Question

Which of the following compounds will produce a precipitate with $AgN{O}_3$ ?

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

Compound which gives $B{r}^{+}$ and becomes a stable carbocation will produce a precipitate of $AgBr$ with $AgN{O}_3$.

Aryl cation are unstable so (a) and (b) does not give precipitate with $AgN{O}_3$.
Also compound (c) gives less stable secondary carbocation so it also does not give precipitate with $AgN{O}_3$.
As it can produce aromatic cation so will produce precipitate with $AgN{O}_3$.
