Arrange the following fractions in order of their boiling points starting from the highest to the lowest: Diesel, Petroleum gas, Lubricating oil, Kerosene, Gasoline

Explanation

To arrange the given fractions in order of their boiling points from highest to lowest, we need to understand the typical boiling point ranges for each of these substances. Here’s the step-by-step solution:

1. **Identify the boiling points of each fraction:**
- **Lubricating Oil:** Typically has a boiling point range of about 200°C to 300°C.
- **Diesel:** Generally has a boiling point range of about 150°C to 300°C.
- **Kerosene:** Usually has a boiling point range of about 150°C to 250°C.
- **Gasoline:** Commonly has a boiling point range of about 30°C to 200°C.
- **Petroleum Gas (LPG):** Has a boiling point range of about -42°C to 0°C.
