Final answer:
Ethanol (C₂H₅OH) has hydrogen bonding.
Step-by-step explanation:
The compound that has hydrogen bonding is ethanol (C₂H₅OH).
Hydrogen bonding occurs when a hydrogen atom is bonded to an electronegative atom, such as oxygen or nitrogen. In ethanol, the hydrogen atom bonded to the oxygen atom can form hydrogen bonds with other ethanol molecules.
Water (H₂O) also exhibits hydrogen bonding because it has hydrogen atoms bonded to oxygen atoms.
