Question

Compound from the following that will not produce precipitate on reaction with Compound from the following that will not produce precipitate on reaction with AgNO₃ is:

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The Correct Option is D

To determine which compound will not produce a precipitate on reaction with silver nitrate (AgNO₃), we need to consider the potential reactions that could occur. Silver nitrate can react with halide ions such as chloride (Cl^-), bromide (Br^-), or iodide (I^-) to form insoluble silver halides (AgCl, AgBr, AgI), which appear as precipitates.

1. When a compound contains a halide, it will react with AgNO₃ to form a precipitate of the corresponding silver halide. For example:
   NaCl (aq) + AgNO₃ (aq) → AgCl (s) + NaNO₃ (aq)
2. Compounds not containing a halide will not give a precipitate with AgNO₃. Typical exceptions include nitrate salts, acetate salts, etc.

Now, let us analyze the given options to find which one does not contain a halogen that would precipitate with AgNO₃:

1. Option 1 - The image shows an alkyl halide, which likely contains a halogen.
2. Option 2 - The image indicates another halide compound.
3. Option 3 - The image shows a third variant of a halide.
4. Option 4 - The image does not include a halogen (like Cl, Br, I).

Therefore, the correct answer is the compound shown in Option 4, as it does not contain a halogen that would lead to the precipitation of a silver halide. Hence, no precipitate is formed upon reacting with AgNO₃.
