As a chemical expert with a focus on inorganic chemistry, I can provide an in-depth explanation as to why solid magnesium chloride does not conduct electricity.
Solid magnesium chloride (MgCl2) is an ionic compound composed of magnesium cations (Mg^2+) and chloride anions (Cl^-). In the solid state, these ions are arranged in a crystal lattice structure where each ion is held in place by strong electrostatic forces of attraction to its neighboring ions. This structure is very stable and rigid, which means that the ions are not free to move around.
Electrical conductivity occurs when charged particles, such as ions or electrons, are able to move freely through a material. In metals, for example, the free electrons are what allow the metal to conduct electricity. However, in the solid state of an ionic compound like magnesium chloride, the ions are not free to move because they are locked into the crystal lattice.
When we consider the statement that "the rest of the chlorides don't conduct electricity either solid or molten because they don't have any ions or any mobile electrons," it's important to clarify that this is not entirely accurate. While it is true that solid ionic compounds do not conduct electricity due to the immobile ions within the crystal lattice, the situation changes when these compounds are in the molten state or dissolved in water.
In the molten state, the heat energy supplied breaks the ionic bonds within the crystal lattice, allowing the ions to move freely. This free movement of ions is what enables molten magnesium chloride to conduct electricity. Similarly, when magnesium chloride is dissolved in water, the compound dissociates into its constituent ions, Mg^2+ and Cl^-, which are then free to move and carry an electric current.
It's also worth noting that the solubility of magnesium chloride in water is quite high, and when it dissolves, it readily dissociates into its ions, making the solution conductive. This is a characteristic behavior of ionic compounds, and it's what allows solutions of salts to conduct electricity.
In summary, the key reason why solid magnesium chloride does not conduct electricity is due to the rigid crystal lattice structure that holds the ions in place, preventing their movement. However, when magnesium chloride is in the molten state or dissolved in water, it can conduct electricity due to the free movement of ions.

The rest of the chlorides don't conduct electricity either solid or molten because they don't have any ions or any mobile electrons. As an approximation, the simple ionic chlorides (sodium and magnesium chloride) just dissolve in water.
