Answer:
Explanation:
We have to keep in mind that a <u>good conductor</u> would be a substance that has the ability to produce <u>ions</u> (<u>charged species</u>). These species are responsible for the electricity conduction on water.
Therefore, we have to check which ones of these compounds will produce <u>ions in water</u>. For and we have <u>diatomic</u> molecules (also gases) this type of molecules don't have the ability to produce ions due to his simplicity, they already are <u>very stable</u>.
In the sugar molecule we have a <u>covalent compound</u>. The ions are produced by <u>ionic compounds</u>. So, this molecule can be discarded too.
For we have an ionic compound that have the ability to produce ions:
So, this is the compound that would be a good conductor due to the and the ions.
