What is the purpose of using a drying agent in organic synthesis?

• A. To enhance reaction rates
• B. To remove water from organic solutions
• C. To increase solubility of compounds
• D. To improve yields of reactions

Answer: (B)

In organic synthesis, the primary purpose of using a drying agent is to remove water from organic solutions. This step is crucial because the presence of water can negatively affect many organic reactions by causing side reactions, hydrolysis, or simply diluting the organic solvents involved in the reaction. For example, during the workup phase of an organic synthesis, residual water can interfere with the extraction of organic products and may lead to lower yields or purity. Drying agents are typically anhydrous salts, such as magnesium sulfate or sodium sulfate, which can absorb water. When added to an organic solution, these agents bind to the moisture present, allowing for a more concentrated and reactive environment conducive to the desired chemical transformations. Additionally, this process improves the overall quality of the final product by ensuring that any water-soluble impurities are minimized. Although enhancing reaction rates, increasing solubility, and improving yields of reactions may have some indirect connection to the use of drying agents, their main function is specifically to ensure the removal of water in order to maintain the integrity of the organic compounds being synthesized.
