The question asks:

Which compound will produce a precipitate with $AgNO_3$?

However, the actual structures/formulae for Options A, B, C, and D are missing in the prompt. Since reaction with $AgNO_3$ depends entirely on the nature of the halogen-containing compound, the options are essential.

1. Principle involved

When an organic halide is treated with $AgNO_3$ (usually alcoholic $AgNO_3$), a precipitate of silver halide may form:

$R-X + Ag^+ \rightarrow AgX \downarrow$

But this happens readily only when the halide ion can be released easily.

Compounds that usually give precipitate readily

• Tertiary alkyl halides
• Allylic halides
• Benzylic halides

These react fast because they form relatively stable carbocations or undergo easy ionization.

Compounds that usually do not give precipitate easily

• Aryl halides (like chlorobenzene, bromobenzene)
• Vinyl halides

This is because the $C-X$ bond has partial double-bond character and is difficult to break.

2. Issue with this question

Since the structures/options are not visible, it is impossible to independently derive whether A, B, C, or D gives the precipitate.

3. Comparison with stored answer

The stored correct answer is B. Because the options are missing, I cannot verify it from first principles.

So I cannot confidently confirm the correctness of B, though I will report the stored answer as the only available answer choice indication.
