Which of the following is an example of a polar solvent fuel?

Acetone is identified as a polar solvent fuel due to its molecular structure and the presence of a carbonyl group (C=O) that allows it to interact with water and other polar substances. Polar solvents typically have a significant dipole moment, meaning they have both positively and negatively charged regions. This characteristic makes acetone capable of solubilizing other polar compounds and explains its role as a solvent in various applications, including industrial processes and cleaning solutions.

In contrast, gasoline, diesel, and hexane are non-polar substances. They are composed primarily of hydrocarbons, which lack polar functional groups, leading to different solubility characteristics. Non-polar solvents do not mix well with water and tend to dissolve non-polar materials instead. Understanding the differences between polar and non-polar solvents is critical for applications involving combustion, chemical reactions, and the handling of various materials in fire scenarios.
