Dimethyl ether and ethyl alcohol are examples of ...................isomerism

Explanation

Functional group Functional Isomerism is the type of isomerism formed by compounds that have same molecular formula but different functional groups. Dimethyl ether and ethanol are said to be isomers that they are different compounds with different functional groups (the -O- ether group and the -OH- alcohol group). Position isomers are constitutional isomers with the same carbon skeleton and will have the same functional group. They differ from each other in the position of the functional groups on the carbon chain. Chain isomerism are the type of isomerism in which moleculer formula is the same but the arrangement of the carbon chain is different. Metamerism are the isomerism having the same molecular formula but different alkyl groups on two sides of functional groups. Reference:Sindh textbook
