Which of the following compounds will most easily conduct electricity when dissolved in water?
CO2
O2
CCl4
MgF 2

Answer:
MgF₂
Explanation:
The correct answer is MgF₂, also known as magnesium fluoride.
This is because magnesium fluoride is an ionic compound, as there's a significant difference between the electronegativities of Mg and F.
Ionic compounds become good electricity conductors once they are dissolved in water.
