Question 11

Crude oil question (6 point)

How crude oil is separated into fractions in terms of structure
Why the fraction can be separated this way

Answer 11

• mention fractional distillation
• heated so crude oil evaporates
• mention different boiling points
• mention different chain length
• mention intermolecular forces
• requires more energy to separate if the intermolecular force is higher
