Here's why:
* Molecular compounds are formed by the sharing of electrons between atoms (covalent bonds). This sharing creates neutral molecules.
* Ionic compounds, on the other hand, are formed by the transfer of electrons between atoms, resulting in charged ions (cations and anions).
* Glucose dissolves in water by forming hydrogen bonds, but it does not dissociate into ions.
Therefore, no ions are produced when glucose dissolves in water.
