The product obtained by the reaction of silver propanoate with bromine in carbon tetrachloride solution is:

Options

A. Bromoethane
B. Silver-3-bromopropanoate
C. Ethanoyl bromide
D. None of the above

Answer

To solve the question regarding the product obtained by the reaction of silver propanoate with bromine in carbon tetrachloride solution, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are silver propanoate (C2H5COOAg) and bromine (Br2) in a carbon tetrachloride (CCl4) solvent.

### Step 2: Understand the Structure of Silver Propanoate
Silver propanoate can be represented as:
- **Structure**: CH3CH2C(=O)O^-Ag^+
This indicates that silver propanoate consists of a propanoate ion (C2H5COO^-) coordinated with a silver ion (Ag^+).

### Step 3: Recognize the Reaction Type
The reaction between silver propanoate and bromine in carbon tetrachloride is known as the **Hund's-Decker reaction**. This is a well-known reaction where a carboxylate reacts with bromine.

### Step 4: Electrophilic Attack
In this reaction, bromine acts as an electrophile. The oxygen atom in the propanoate ion has a negative charge, making it a nucleophile. The nucleophilic oxygen will attack the electrophilic bromine, leading to the formation of a brominated product.

### Step 5: Formation of Bromopropanoate
The nucleophilic attack results in the formation of **bromopropanoate** (C2H5COBr) and sodium bromide (NaBr) as a side product.

### Step 6: Homolytic Cleavage
Upon further reaction, a homolytic cleavage can occur, generating radicals. The oxygen-bromine bond can break, leading to the formation of an oxygen radical and a bromine radical.

### Step 7: Radical Reactions
The ethyl radical generated can then react with the bromine radical to form **bromoethane** (C2H5Br) as the major product of the reaction.

### Step 8: Conclusion
The major product obtained from the reaction of silver propanoate with bromine in carbon tetrachloride is **bromoethane**.

### Final Answer
The product obtained by the reaction of silver propanoate with bromine in carbon tetrachloride solution is **bromoethane**.
