Question:
Number of carbon atoms in kerosene is:
Number of carbon atoms in kerosene is:
Show Hint
Kerosene range: \(C_{12} - C_{16}\) (medium chain hydrocarbons).
Updated On: Apr 16, 2026
- \(C_{17} - C_{20}\)
- \(C_{12} - C_{16}\)
- \(C_{20} - C_{25}\)
- \(C_{25} - C_{30}\)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Petroleum refining separates crude oil into fractions based on boiling point ranges, which correspond to different carbon chain lengths.
Step 1: Recall fractional distillation ranges.
Common fractions and their carbon ranges:
• Petroleum gas: \(C_1 - C_4\)
• Petrol (gasoline): \(C_5 - C_{10}\)
• Naphtha: \(C_6 - C_{12}\)
• Kerosene: \(C_{12} - C_{16}\)
• Diesel: \(C_{14} - C_{20}\)
• Fuel oil: \(C_{20} - C_{30}\)
• Residue (bitumen): \(> C_{30}\)
Step 2: Identify kerosene range.
Kerosene contains hydrocarbons with approximately 12 to 16 carbon atoms per molecule.
