Which of the following is property of salts •undergo combustion •do not make iconic bonds easily •do not conduct electricity as solids •formed due to reaction of acid with water

Option (c) is the correct answer.

Explanation:

For a compound to conduct electricity, it is necessary that it should be present in molten state that is, there should be ions.

For example, a solution of NaCl is able to conduct electricity because it contains sodium ions and chlorine ions.

But a salt present in solid state is not able to conduct electricity because molecules are not present in ionic form. When this solid is dissolved in water then its molecules convert into ions and only then it will be able to conduct electricity.

Thus, we can conclude that salts do not conduct electricity as solids is property of salts.
