Answer

Ethanol and Ethylene Glycol

Procedure

Hydrogen bonding occurs when hydrogen forms a molecular bond with a highly electronegative element such as Oxygen, Nitrogen, and Fluorine. Based on the structure of the molecules we can see that ethane does not contain the previously mentioned elements, therefore it will not form hydrogen bonds. Dimethyl ether has an oxygen atom located in the middle of the molecule, making it difficult to form a bond with other dimethyl ether molecules.

Lastly, Ethanol and Ethylene Glycol possess OH groups which are free to interact with similar groups via hydrogen bonding. Additionally, these last compounds exhibit higher boiling points, which can indicate a stronger intermolecular bonding, which is a characteristic of hydrogen bonding.
