Answer:
MgCl₂. Option B is correct
Explanations:
What are polar solvents?
A polar solvent is a type of solvent that has partial charge and dipole moments. They tend to dissolve ions and other polar compounds.
The molecules in a polar solvent have a dipole, like water, one side is more negative and one is more positive.
Ionic compounds are composed of a positive ion, normally a metal, and a negative ion, normally a nonmetal, so their forces are attracted to their charge difference.
Thus, a polar solvent dissolves each ion with its corresponding parts, dissociating the two ions of the ionic compound.
Based on the explanation above, C6H12O6 being a covalent compound cannot dissociate into ions hence can not dissolve in a polar solvent.
MgCl₂ on the other hand is highly soluble in water and can dissociate to form Mg2+ and Cl-. Hence the substances would undergo dissociation when placed into a polar solvent is MgCl₂
