Testing ethers for the presence of peroxides

The Grignard Reagent

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

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

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

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

Cyclic Ethers
