Representations of Solutions Practice Test

Hydrogen bonding between the O–H group of ethanol and water molecules, with ethanol molecules remaining intact.

Electrostatic attraction between C$_2$H$_5^+$ and OH$^-$ produced by complete dissociation of ethanol in water.

Ion–dipole attractions between C$_2$H$_5$OH$^+$ ions and water because ethanol ionizes in water.

Covalent bond formation between ethanol and water to produce hydrates that are new compounds in solution.

Only London dispersion forces between ethanol and water because both molecules are nonpolar overall.
