Question

Which of the following compounds will most easily conduct electricity when dissolved in water?

CO2

O2

CCl4

MgF 2

Answer 1

MgF₂

Step-by-step 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.
