Which of the following compounds will NOT conduct electricity. If It is dissolved it KNO_(3) HCl (acid) CH_(3)OH NaI

The compound that will NOT conduct electricity when dissolved is $CH_{3}OH$ (methanol).<br /><br />Methanol is a molecular compound and does not dissociate into ions when dissolved in water. In contrast, $KNO_{3}$, HCl, and NaI are ionic compounds that dissociate into ions when dissolved in water, allowing them to conduct electricity.
