Because in order for a solution to conduct electricity, it must be an electrolyte - that is, it must contain free ions (charged particles). HCl, or hydrochloric acid, dissolves freely in water, with its ionic bonds releasing to create H+ and Cl- ions in solution. This happens because Hydrogen is able to release its electron, and Chlorine has a high affinity for electrons, so when the two of them join, the bond they create actually involves a tranfer of electrons from H to Cl; when this bond is broken the electrons stay with the Cl, creating ions. The presence of these ions allows electricity to flow through the solution, thus making it a conductor.
Glucose is not an ionic substance. The bonds that hold this molecule together are covalent, meaning that electrons are shared rather than transferred from one atom to another. This occurs because Carbon, which has 4 valence (outer shell) electrons, is able to hold onto its own electrons and share them with other atoms such as Oxygen.

Hey dear buddy..
Here's is ur answer ^______^.
HCL conduct electricity becoz hcl give more H^+ ions in water and glucose have no ions so it not conduct electricity.
Dear;) hope its helps ☺
