Ether
Related compounds

Many classes of compounds with C–O–C linkages are not considered ethers: Esters (R–C(=O)–O–R′), hemiacetals (R–CH(–OH)–O–R′), carboxylic acid anhydrides (RC(=O)–O–C(=O)R′).

There are compounds which, instead of C in the C−O−C linkage, contain heavier group 14 chemical elements (e.g., Si, Ge, Sn, Pb). Such compounds are considered ethers as well. Examples of such ethers are silyl enol ethers R Si−O−CR=CR (containing the Si−O−C linkage), disiloxane H Si−O−SiH (the other name of this compound is disilyl ether, containing the Si−O−Si linkage) and stannoxanes R Sn−O−SnR (containing the Sn−O−Sn linkage).
