Question

Ether
and alcohol
are​. 1)chain isomer 2)functional isomer 3) position isomer 4)metamer
​

Answer 1

Ethers contain the Alkoxy functional group in them.

Alcohols contain the Hydroxyl functional group in them

So, they may have the same molecular formula but have different structural formula and different functional groups.

So, they are functional isomers.

For example, Dimethyl ether or Methoxy methane(H3C-O-CH3) and Ethanol (C2H5OH) have the same molecular formula of C2H6O but they have different functional groups, so they are functional isomers.
