Mark the correct sequence of substances obtained during fractional distillation of petroleum in ascending order of their boiling points.

Options

A. Petroleum gas, Kerosene, Petrol, Diesel, Paraffin wax
B. Petrol , petroleum gas ,kerosene , Light crude oil diesel
C. Petroleum gas , petrol , kerosene diesel , Lubricating oil
D. petroleum gas , petrol , Lubricating oil , diesel , kerosene

Explanation

To solve the question regarding the correct sequence of substances obtained during fractional distillation of petroleum in ascending order of their boiling points, we can follow these steps:

### Step 1: Understand Fractional Distillation
Fractional distillation is a process used to separate a mixture into its individual components based on their boiling points. When a mixture is heated, components with lower boiling points vaporize first.

### Step 2: Identify the Substances and Their Boiling Points
We need to list the substances obtained from fractional distillation of petroleum along with their boiling point ranges:

1. **Petroleum Gas**: Below 40°C
2. **Petrol**: 40°C to 75°C
3. **Kerosene**: 160°C to 250°C
4. **Diesel**: 250°C to 300°C
5. **Lubricating Oil**: 300°C to 350°C

### Step 3: Arrange the Substances in Ascending Order of Boiling Points
Now, we will arrange these substances in ascending order based on their boiling points:

1. **Petroleum Gas**: Below 40°C
2. **Petrol**: 40°C to 75°C
3. **Kerosene**: 160°C to 250°C
4. **Diesel**: 250°C to 300°C
5. **Lubricating Oil**: 300°C to 350°C

### Step 4: Write the Final Sequence
The final sequence of substances in ascending order of their boiling points is:
- Petroleum Gas
- Petrol
- Kerosene
- Diesel
- Lubricating Oil

### Conclusion
Thus, the correct answer is:
**Petroleum Gas < Petrol < Kerosene < Diesel < Lubricating Oil**
