A petroleum fraction having boiling range `70-200^(@)C` and cotaining 6 - 10 carbon atoms per molecule is called

Options

A. Natural gas
B. Gas oil
C. Gasoline
D. Kerosene

Answer

To solve the question regarding the classification of a petroleum fraction based on its boiling range and carbon atom count, we can follow these steps:

### Step 1: Understand the given data
The question states that we have a petroleum fraction with:
- Boiling range: 70 to 200 °C
- Carbon atoms per molecule: 6 to 10

### Step 2: Analyze the options
The options provided are:
- Natural gas
- Gas oil
- Gasoline
- Kerosene

### Step 3: Recall the characteristics of each option
1. **Natural Gas**: Primarily consists of methane (1 carbon atom) and other light hydrocarbons. It has a very low boiling point and does not fit the given boiling range.
2. **Gas Oil**: Typically has a higher boiling point, usually above 200 °C, and contains more carbon atoms (generally more than 10).
3. **Gasoline**: Known to have a boiling range of about 30 to 200 °C and typically contains 5 to 12 carbon atoms, which fits our criteria of 6 to 10 carbon atoms.
4. **Kerosene**: Generally has a boiling range of about 150 to 300 °C and contains around 10 to 16 carbon atoms, which does not match our criteria.

### Step 4: Identify the correct answer
Based on the analysis, the only option that matches both the boiling range of 70 to 200 °C and the carbon atom count of 6 to 10 is **Gasoline**.

### Final Answer
The correct answer is **Gasoline**.
