Such compounds are often classified as methoxides. cyst under tooth rootWebFor example, a methyl group attached to an oxygen, OCH 3, is named as a methoxy group. In cyclic ethers, the prefix oxa-is used to indicate replacement of a carbon by an oxygen. Since ethers do not have a hydrogen connected to the oxygen atoms, they are not capable of forming hydrogen bonds to each other. cyst under eyelid treatment
