Final answer:
Yes, biphenyl is soluble in ethyl acetate. Biphenyl, a non-polar compound, is expected to be soluble in ethyl acetate, a relatively non-polar solvent, according to the 'like dissolves like' principle commonly applied in chemistry.
Step-by-step explanation:
The student is asking whether biphenyl is soluble in ethyl acetate. Ethyl acetate is an ester that is frequently used as a solvent in various chemical applications. Biphenyl is a non-polar organic compound consisting of two benzene rings connected by a single bond. The solubility of a substance in a solvent is generally predicted by the principle of 'like dissolves like,' which suggests that non-polar compounds tend to be soluble in non-polar solvents, while polar compounds are soluble in polar solvents.
Given the non-polar nature of biphenyl and the relatively non-polar character of ethyl acetate, it would be expected that biphenyl is soluble in ethyl acetate. This concept is also supported by common laboratory practices where ethyl acetate is used in extractions to dissolve non-polar substances from mixtures.
