Which of the following substances, when dissolved in water, gives the poorest conduction of electric current?
- Ethanoic acid, C2H4O2
- Hydrogen chloride, HCl
- Ammonia, NH3
- Fructose, C6H12O6
Correct answer: Fructose, C6H12O6
Solution
Fructose is a non-electrolyte, meaning it does not dissociate into ions when dissolved in water, resulting in poor conductivity of electric current compared to the other options, which are electrolytes that ionize.
