1 When epoxides react, they undergo ring-opening by a cleavage of the C-O bond. Why is it easier to break a C-O bond of an epoxide compared to breaking a C-O bond of other ethers? A. A more stable carbocation is formed when an epoxide ring-opens. B. Breaking the epoxide C-O bond relieves the strain of a three-member ring. C. Epoxide ring opening conforms to a faster E2 mechanism.

Introduction
Epoxides are cyclic ethers that contain a three-membered ring consisting of two carbon atoms and one oxygen atom. They have unique chemical properties due to the ring strain caused by the angle strain of the C-O-C bond angle. Epoxides can undergo ring-opening reactions, which make them versatile intermediates in organic synthesis. They are widely used as building blocks in the production of various organic compounds such as pharmaceuticals, agrochemicals, and polymers.
