Fraction Typical Hydrocarbon Chain Length Boiling Point Range (°C) Position in Column Common Uses
Refinery Gas C₁ – C₄ Below 40°C Top Heating and cooking gas
Gasoline (Petrol) C₅ – C₁₀ 40 – 110°C Upper Section Fuel for cars
Naphtha C₇ – C₁₄ 110 – 180°C Upper-Middle Chemical feedstock (plastics)
Diesel Oil C₁₄ – C₂₀ 250 – 350°C Lower-Middle Fuel for diesel engines
Bitumen C₇₀+ Above 350°C Bottom Road surfacing

🔑 Key Trend Reminder

Moving up the fractionating column:
→ Hydrocarbon chain length decreases
→ Boiling point decreases
Moving down the fractionating column: 
→ Hydrocarbon chain length increases
→ Boiling point increases
