Which of the following compounds is a nonelectrolyte? a. sodium bromide b. magnesium sulfate c. carbon tetrachloride d. calcium hydroxide

Option (C) is the correct answer.

Explanation:

An electrolyte is defined as the substance which when dissolved in water dissociates into ions and it is able to conduct electricity.

Ionic compounds are the compounds which are soluble in water as ;like dissolves like.

Hence, water being a polar solvent is able to dissolve ionic compounds.

Sodium bromide and calcium hydroxide are ionic compounds. So, they act as an electrolyte as they dissociate into ions in water.

Whereas magnesium sulfate is also soluble in water as solubility of sulfates of group 2A decreases down the group.

On the other hand, is a non-polar compound. Hence, it will not dissociate into ions when dissolved in water.

Thus, we can conclude that carbon tetrachloride compound is a non-electrolyte.
