Solid NaCl is a bad conductor of electricity because : — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Electrical conductivity in a substance requires the presence of mobile charged carriers (either free electrons or mobile ions). Step 2: Solid sodium chloride is a crystalline ionic compound composed of Na^+ and Cl^- ions held tightly and rigidly in fixed positions in a 3D lattice by strong electrostatic forces. Step 3: Because these ions cannot migrate or move freely in the solid phase, solid NaCl lacks ionic mobility and is a non-conductor of electricity. This corresponds to option (c).
