WebStructural formula of isoflurane, a typical halogenated ether. The C—O—C (carbon-oxygen-carbon) in the center is the ether group and the Cl (chlorine) and F (fluorine) are the halogen atoms, which have been substituted for all but two H (hydrogen) atoms. A halogenated ether is a subcategory of a larger group of chemicals known as ethers. Weban OH group replaces the halogen (X) is an example of nucleophilic substitution. Most nucleophilic substitution reactions take place by either the SN1 or the SN2 mechanism. The SN1 mechanism has an intermediate carbocation with a positive charge on a carbon atom. Carbocation intermediates are planar and stabilized by alkyl groups.
