it does not have any hygrogen ions in it
To conduct electricity either free electrons or free ions are needed. Glucose has the following structure
being non polar compound, no ion is formed in solution,moreover there is no free electrons thus it doesnt conduct electricity in solid,liquid or aquoeus state
Glucose doesn't conduct electricity because it's a covalent compound. Covalent compounds have no free and delocalised electrons to move about, as they have a stable electronic configuration.
You might think what about concentrated glucose or aqueous glucose. But they cannot be dissociated by the water molecules as they have neutral charges.
