What is the number of carbon atoms in alkanes found in diesel?
Options
- AC ₂₉ to C ₃₁
- BC ₆ to C ₈
- CC ₁ to C ₄
- DC ₁₅ to C ₁₈
Correct answer
D. C ₁₅ to C ₁₈
Step-by-step solution
Diesel fuel consists mainly of paraffins, aromatics and naphthenes. The hydrocarbons of gasoline contain typically 4-12 carbon atoms with boiling range between 30 and 210 °C, whereas diesel fuel contains hydrocarbons with approximately 15–18 carbon atoms and the boiling range is between 170 and 360 °C.
