Question

When crude oil is distilled, it is separated into categories. What are those categories characterized by?

Answer 1

Answer:

Differences in their boiling points

Explanation:

When crude oil is distilled and separated into categories, the categories are characterized by the differences in their boiling points.

At different boiling points, each of the fraction will separate out.

• Crude oil is made up of different fractions of hydrocarbons.
• As the chain length of the hydrocarbon increases, the volatility reduces and boiling point increases.
• Components with short carbon lengths rises out from the column first and are cooled and extracted.
• The categories are thereby, classified based on differences in their boiling points.
