Biphenyl is commonly obtained as an impurity during the synthesis of Grignard synthesis of benzoic acid from bromobenzene. How would you detect the presence of biphenyl in your product with a TLC experiment? (Explain what type of solid phase you would use and what type of solvent you would select as an eluting solvent, to detect the biphenyl impurity.)
