A mixture of benzene and toluence forms

Options

A. An ideal solution
B. Non-ideal solution
C. Suspension
D. Emulsion

Explanation

To determine the type of solution formed when benzene and toluene are mixed, we can follow these steps:

### Step 1: Understand the Components
Benzene (C6H6) and toluene (C7H8) are both aromatic hydrocarbons. They have similar structures and properties, which is important for understanding their interactions when mixed.

**Hint:** Consider the molecular structure and properties of both benzene and toluene.

### Step 2: Analyze the Interaction Forces
When benzene and toluene are mixed, we need to examine the interaction forces between the molecules. In this case, the mixing does not involve any significant change in the interaction forces between the molecules of benzene and toluene.

**Hint:** Think about how similar molecules interact with each other compared to how different molecules might interact.

### Step 3: Identify the Type of Solution
Since the mixing of benzene and toluene does not lead to any decrease or increase in interaction forces, we can conclude that they form an ideal solution. An ideal solution is one where the enthalpy of mixing is zero, meaning there is no energy change when the two substances are mixed.

**Hint:** Recall the definition of an ideal solution and what conditions must be met for a solution to be considered ideal.

### Step 4: Conclusion
Based on the analysis, we conclude that the mixture of benzene and toluene forms an ideal solution.

**Final Answer:** The type of solution formed when benzene and toluene are mixed is an **ideal solution**.
