Final answer:
An aqueous solution of ethanol does not conduct electricity due to the absence of dissolved ions. However, an aqueous solution of ethanoic acid conducts electricity because it forms ions when dissolved in water.
Step-by-step explanation:
An aqueous solution of ethanol does not conduct electricity because it does not contain dissolved ions. Ethanol is a non-electrolyte, meaning it does not ionize in water. On the other hand, an aqueous solution of ethanoic acid, also known as acetic acid, conducts electricity because it ionizes in water to form ions. Ethanoic acid is a weak electrolyte, meaning it partially ionizes in water.
