Verified step by step guidance
1
Identify the structure of aspirin from the image: Aspirin is an aromatic compound with a carboxylic acid group and an ester group attached to a benzene ring.
Recall the principle 'like dissolves like': Polar solvents dissolve polar compounds, and nonpolar solvents dissolve nonpolar compounds.
Analyze the polarity of aspirin: The presence of the carboxylic acid and ester groups makes aspirin a polar molecule.
Evaluate the polarity of the given solvents: Hexane is nonpolar, acetone is polar, and toluene is slightly polar due to the benzene ring.
Determine which solvent is most likely to dissolve aspirin: Since aspirin is polar, acetone, being a polar solvent, is expected to dissolve aspirin effectively.
