Which of the following is probably the poorest electrical conductor?

Compounds which give ions when dissolved in water will form conductive solutions. a) and c) are ionic compounds which are expected to dissociate to ions; b) is a weak acid which will give low concentrations of H+ and F-; d) is a weak base which will give low concentrations of NH4+ and OH-. But e) is a covalent organic compound lacking appreciable acid-base properties, and, likewise, adding it to water is not expected to raise the conductivity appreciably.
