WebAlthough ethers contain two polar carbon-oxygen bonds, they are much less reactive than alcohols or phenols. Can an ether be in a ring? Cyclic ethers can be considered … WebCyclic ethers which are also known as epoxides can be prepared: By the oxidation of alkenes with a peroxyacid such as m-CPBA . By the base intramolecular nuclephilic substitution of a halohydrin. Reactions Ethers in general are of very low chemical reactivity. Organic reactions are: Hydrolysis .
WebThe boiling points of CH3F, CH3Cl, CH3Br, and CH3I are -75°C, -24°C, 3.5°C, and 42.5°C. Reactions of the first three would have to be conducted at low temperatures, and this would make the reaction too slow to be practical. No matter the temperature, the order of reactivity is F < Cl < Br < I. So you should use CH3I.
