Organic Chemistry

Simple explanation

Crude oil is a mixture of hydrocarbons.

Analogy or example

Petrol fractions contain shorter hydrocarbons than bitumen.

Misconception trap

Fractional distillation creates new substances.

Real-world relevance

Crude oil links classroom reactions to materials, energy, resources and everyday products.
