CH\(_3\)-CH\(_2\)-OH and CH\(_3\)-O-CH\(_3\)

The relationship between the two compounds above, is that they are 

allotropes
isotopes
isomers
isobars

Explanation

CH3-CH2-OH and CH3-O-CH3 are functional isomers, meaning they have the same molecular formula but different functional groups: 

  • CH3-CH2-OH: This is the chemical formula for ethanol, an alcohol. The structure of ethanol is an ethyl group linked to a hydroxyl group. 

  • CH3-O-CH3:This is the chemical formula for dimethyl ether, an ether. The structure of dimethyl ether is R – O – R, where R is alkyl groups.
