Chemistry - STRUCTURAL ISOMERISM Question with Solution | TestHub

A mixed ether has two different groups on oxygen (R-O-R'). Because the two alkyl (or aryl) groups are different, it is called an unsymmetric ether. Symmetric ethers carry two identical groups, 'dialkyl ethers' describes the general class, and oxane is the IUPAC name of the six-membered cyclic ether.
