Question

Using the cross-section image of an iodine solid, which of the following explains why it cannot conduct electricity in the solid or molten states?

• A. The molecular lattice points are too far away to conduct electricity.
• B. Only metallic solids conduct electricity.
• C. The electrons are tightly bound within the covalent bond of the $I_2$ molecules.
• D. The electrons are too polarizable to conduct electricity.

Answer 1

The correct option is C The electrons are tightly bound within the covalent bond of the $I_2$ molecules.

$I_2$ cannot conduct electricity in solid or in molten state as free $e^{-}$ are not available for carrying current.
