A TLC analysis is performed on both crude and purified biphenyl. Upon visualization under the UV- lamp both spots remain at the baseline. This is likely because: a. Biphenyl is a polar molecule and therefore should remain at the baseline upon TLC plate development in the proper eluent. b. The samples were not spotted properly on the TLC plate. c. The solvent was too non-polar. d. The solvent was too polar. e. The solvent evaporated before the TLC plate could be added to the chamber.
