Acid-catalyzed condensation is impractical for the synthesis of the unsymmetrical ether shown below. Explain why this is true.
isopropyl propyl ether, (CH₃)₂CH−O−CH₂CH₂CH₃

• A. The acid-catalyzed condensation requires a strong acid, which is not commercially available.
• B. The acid-catalyzed condensation produces a mixture of ethers with similar boiling points, which makes it difficult to isolate the desired product.
• C. The acid-catalyzed condensation gives a high yield of the product, which is undesirable.
• D. The acid-catalyzed condensation gives water-insoluble products, which is undesirable.
