Gasoline produced by the fractional distillation of petroleum is:
Correct answer: D. 20%
- A. 80%
- B. 50%
- C. 65%
- D. 20%
Explanation
Fractional distillation is a process used in the refining of crude oil to separate its components based on their boiling points. In this process, crude oil is heated, and the vaporized components are then condensed at different temperatures to obtain various fractions. Gasoline is one of these fractions, and its percentage in the final product depends on the boiling range of the crude oil and the temperature ranges at which different fractions are collected. While gasoline typically falls within the 20-50% range, the specific percentage can vary due to factors such as the composition of the crude oil being processed and the refining techniques employed by a particular refinery. Different refineries may produce gasoline with varying characteristics based on their operational parameters. Therefore, option D is correct.

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.
