Final answer:
None of the listed compounds - sodium chloride, ethanol, sucrose, or iron - will dissolve well in carbon tetrachloride (CCl₄) as CCl₄ is a nonpolar solvent, and the compounds are either polar or metallic and do not form true solutions in nonpolar solvents.
Step-by-step explanation:
The question is which compound listed below will dissolve in carbon tetrachloride (CCl₄). The key principle to consider here is 'like dissolves like', which means that polar substances tend to dissolve in polar solvents and nonpolar substances tend to dissolve in nonpolar solvents. Carbon tetrachloride is a nonpolar solvent.
- Sodium chloride (NaCl): This is an ionic compound and polar, so it will not dissolve well in a nonpolar solvent like CCl₄.
- Ethanol (C₂H₅OH): Ethanol is a polar molecule due to its hydroxyl (-OH) group. It can form hydrogen bonds and is miscible with water, making it not a good candidate for dissolving in CCl₄.
- Sucrose (C₁₂H₂₂O₁₁): Sucrose is also polar, and because it can form hydrogen bonds with water, it will not dissolve well in CCl₄.
- Iron (Fe): This is a metallic element and does not form true solutions when mixed with solvents like CCl₄.
None of the compounds listed would be expected to dissolve well in carbon tetrachloride due to their polar nature or, in the case of iron, being a metal.
