What category do solvents like acetone and methyl ethyl ketone belong to?

Solvents such as acetone and methyl ethyl ketone (MEK) are classified as ketones. Ketones are a group of organic compounds characterized by the presence of a carbonyl group (C=O) bonded to two carbon atoms. Acetone, also known as propanone, is the simplest ketone and is often used as a solvent in various applications, including paint thinners and nail polish removers. Similarly, methyl ethyl ketone, with its more complex structure, retains the carbonyl feature that defines ketones.

This classification is essential as it determines the chemical properties and applications of these solvents. Ketones generally have higher evaporation rates than other solvent classes like alcohols and esters, influencing their use in industrial and laboratory settings. Understanding these categories helps in correctly selecting solvents for specific tasks, ensuring safety and effectiveness based on their chemical behavior.
