Final answer:
Carbon tetrachloride is not soluble in water and does not conduct electricity, while sodium chloride is highly soluble in water and does conduct electricity.
Step-by-step explanation:
Carbon tetrachloride and sodium chloride have different properties when it comes to solubility in water and electrical conductivity.
1. Solubility in water: Carbon tetrachloride is not soluble in water because it is a nonpolar compound, meaning it does not have a positive or negative charge and cannot form hydrogen bonds with water molecules. On the other hand, sodium chloride is highly soluble in water because it is an ionic compound consisting of positively charged sodium ions and negatively charged chloride ions, which interact with water molecules through ion-dipole interactions.
2. Electrical conductivity: Carbon tetrachloride does not conduct electricity because it does not dissociate into ions in water. Sodium chloride, on the other hand, does conduct electricity when dissolved in water or in its molten form because it dissociates into sodium and chloride ions, which are free to move and carry an electric charge.
