Which of the following is true about the conductivity of simple molecular substances?

Simple molecular substances are typically made up of molecules that consist of covalently bonded atoms. These substances do not contain charged particles such as ions or free electrons that are necessary for conducting electricity. In solid or liquid states, these molecules are held together by intermolecular forces, which are generally weak and do not facilitate the movement of electrical charge. Therefore, because simple molecular substances do not dissociate into ions or possess free-moving electrons, they are unable to conduct electricity, making the statement that they do not conduct electricity accurate.

In contrast, options that suggest they conduct electricity well, are excellent insulators, or only conduct when hot imply a presence of charge carriers that these substances lack.
