Draw for all constitutional isomers that have molecular formula C2H6O2

Explanation:

Two or more compounds are said to be isomers if they have the same molecular formula but different structures.

Isomers that have the same molecular formula but different connectivity are largely regarded as constitutional isomers.

From below, we can see the different constitutional isomers of C2H6O2.

CH₃ - CH₂ - O - O - H  

(c)

     |                |

 CH₂    --     CH₂

(d)

           OH

            |

CH₃ -- CH
