Final answer:
Dichloromethane (DCM) is a good organic solvent to solubilize benzoic acid and acetanilide because it has a low polarity and can dissolve a variety of organic compounds.
Step-by-step explanation:
Dichloromethane (DCM) is a good organic solvent to solubilize benzoic acid and acetanilide because it has a low polarity and can dissolve a variety of organic compounds. Unlike water, which is a polar solvent, DCM is nonpolar and can interact with nonpolar molecules like benzoic acid and acetanilide. This allows the solvent to solubilize these compounds, which have both polar and nonpolar regions.
