WebEthers are known as dialkyl (R-O-R ’), alkyl aryl (Ar-O-R),or diaryl (Ar-O-Ar ’)derivatives of water. If the two groups attached on the sides are identical, the ether formed is symmetrical; otherwise, it is referred to as an unsymmetrical ether structure. Examples include dimethyl ether (symmetrical) and ethyl methyl ether (unsymmetrical). WebScore: 4.6/5 (1 votes) . Williamson Ether Synthesis usually takes place as an S N 2 reaction of a primary alkyl halide with an alkoxide ion.The structure of ethers was proved due to this chemical reaction. S N 2 pathway is required for the synthesis this reaction is useful only when the alkyl halide is primary or secondary. eskom northern cape contact details
