Explain metamerism with suitable examples of ethers
Metamerism (positional isomerism): Ethers having same molecular formula but different alkyl groups attached on either side of the oxygen atom are called metamers of each other. This phenomenon is called metamerism (positional isomerism).
eg. Ethers with molecular formula C4H10O have three metamers having different alkyl groups attached on either side of oxygen atom.

- CH3-O-CH2-CH2-CH3 Methyl n-propyl ether
- CH3-O-C2H4-CH3 Isopropyl methyl ether
