What is the primary feature of esters?

• A. They have ammonia-like properties
• B. They are formed from carboxylic acids and alcohols
• C. They contain a hydroxyl group
• D. They are always solids at room temperature

Answer: (B)

The primary feature of esters is that they are formed from the reaction of carboxylic acids and alcohols. In this process, a condensation reaction occurs, in which one molecule of water is eliminated. This results in the formation of an ester bond, characterized by the connection between the carbonyl group (C=O) of the carboxylic acid and the oxygen atom of the alcohol. The formation of esters is crucial in organic chemistry, as it gives rise to a wide variety of compounds that are often found in natural products and used in fragrances, flavorings, and biofuels. Understanding this fundamental process is essential for recognizing the structural characteristics and reactivity of esters in various chemical contexts.
