Which of the following fractions is NOT typically obtained from crude oil?

Crude oil is a complex mixture composed primarily of hydrocarbons and is processed in refineries through various methods such as distillation to separate it into different fractions. The common fractions obtained from crude oil include refinery gases, gasoline, and diesel.

Refinery gases are light hydrocarbons that evaporate during the distillation of crude oil and are typically used as fuel in the refinery or for heating purposes. Gasoline is obtained from the fraction of crude oil that boils between 40°C and 205°C and is widely used as a fuel for internal combustion engines. Diesel is derived from a higher boiling point range of crude oil and serves as fuel for diesel engines.

In contrast, coal is not a fraction derived from crude oil. It is a separate fossil fuel that forms from the remains of ancient plant matter compressed under heat and pressure over millions of years. Therefore, coal does not originate from crude oil and is not produced during the refining process, making it the correct response to the question.
