B) If the sign of w is negative, the reaction is always exothermic. C) If ΔE is negative, the reaction is always exothermic. D) When the surroundings gains heat, the reaction is exothermic. WebEpoxide. In organic chemistry, an epoxide is a cyclic ether, where the ether forms a three-atom ring: two atoms of carbon and one atom of oxygen. This triangular structure has substantial ring strain, making epoxides highly reactive, more so than other ethers. They are produced on a large scale for many applications.
