The crude petroleum is separated in fractions by:

Correct answer: B. Fractional distillation

  • A. Filtration
  • B. Fractional distillation
  • C. Steam distillation
  • D. Fractions sublimation

Explanation

Crude petroleum is separated into fractions through fractional distillation, a process that takes advantage of the differences in boiling points of its components. In a fractional distillation column, crude petroleum is heated, and the vapors rise through the column. As the vapors cool at different heights in the column, they condense into liquid fractions, each containing hydrocarbon molecules with similar boiling points.

About Fundamental Principles of Organic Chemistry

Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
