When a mixture of sulfur dioxide and chlorine are made to react with sulfur dichloride the product formed is:

Options

A. (A) sulfuryl chloride
B. (B) thionyl chloride
C. (C) sulfur trioxide
D. (d) phosphine

Answer

To solve the question about the reaction between a mixture of sulfur dioxide (SO2) and chlorine (Cl2) with sulfur dichloride (SOCl2), we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are:
- Sulfur dioxide (SO2)
- Chlorine (Cl2)
- Sulfur dichloride (SOCl2)

### Step 2: Understand the Reaction
When sulfur dioxide reacts with chlorine, it can form sulfur dichloride. The reaction can be represented as:
\[ \text{SO}_2 + \text{Cl}_2 \rightarrow \text{SOCl}_2 \]

### Step 3: Write the Balanced Equation
To balance the equation, we need to ensure that the number of each type of atom is the same on both sides. The balanced equation is:
\[ \text{SO}_2 + \text{Cl}_2 \rightarrow \text{SOCl}_2 \]

### Step 4: Identify the Product
From the balanced equation, we can see that the product formed from the reaction of sulfur dioxide and chlorine with sulfur dichloride is:
- Thionyl chloride (SOCl2)

### Conclusion
Thus, the product formed when a mixture of sulfur dioxide and chlorine reacts with sulfur dichloride is thionyl chloride (SOCl2).

### Final Answer
The correct option for the given question is **B: Thionyl chloride (SOCl2)**.
