What will be the correct order of vapour pressure of water, acetone and ether at `30.^(@)C`. Given that among these compounds, water has maximum boiling point and ether has minimum boiling point ? (A)Water < Ether < Acetone (B)Water < Acetone < Ether (C)Ether < Acetone < Water (D)Acetone < Ether < Water

Options

A. Water `lt` Ether `lt` Acetone
B. Water `lt` Acetone `lt` Ether
C. Ether `lt` Acetone `lt` Water
D. Acetone `lt` Ether `lt` Water

Explanation

To determine the correct order of vapor pressure of water, acetone, and ether at 30°C, we need to consider the relationship between boiling points and vapor pressures.

### Step-by-Step Solution:

1. **Understand the Relationship**:
- The vapor pressure of a liquid is inversely related to its boiling point. This means that a liquid with a higher boiling point will have a lower vapor pressure at a given temperature, and vice versa.

2. **Identify the Boiling Points**:
- According to the information provided:
- Water has the maximum boiling point.
- Ether has the minimum boiling point.
- Acetone has a boiling point that is in between water and ether.

3. **Determine the Vapor Pressure Order**:
- Since water has the highest boiling point, it will have the lowest vapor pressure.
- Ether, having the lowest boiling point, will have the highest vapor pressure.
- Acetone, being in between, will have a vapor pressure that is higher than that of water but lower than that of ether.

4. **Establish the Order**:
- Therefore, the order of vapor pressure from lowest to highest is:
- Water < Acetone < Ether

5. **Select the Correct Option**:
- Based on the established order, the correct answer is:
- (B) Water < Acetone < Ether

### Final Answer:
(B) Water < Acetone < Ether
