  1. Organic chemistry for medicine and biology students Chem 2311 Chapter 8 Ethers By Prof. Dr. Adel M. Awadallah Islamic University of Gaza

  2. Preparation of Ethers • Symmetrical ethers (from alcohols) B) Unsymmetrical ethers (Williamson’s Synthesis)

  3. Cleavage of Ethers Ethers are cleaved by strong acids such as HI

  4. Epoxides (Oxiranes) Cyclic ethers with a three-membered rings

  5. Reactions of Epoxides When attacked by nucleophiles, epoxides undergo acid catalized ring opening.

  6. Cyclic Ethers
