(b) Describe the change in composition of the solution containing a mole fraction of 0.10 A as the temperature increases from 132 to 133°C? 138 136 134 132 130 0.00 0.20 0.40 0.60 0.80 1.00 XA . Why must the spot be applied to the TLC plate above the level of development solvent? A Grignard reaction of phenylmagnesium bromide with 3-pentanone gives 3-phenylpentan- 3-ol as the major product (we will discuss this reaction later). The crude product contains the 3-phenylpentan-3-ol product, unreacted 3-pentanone, and biphenyl (a side product). A developing solvent is found that separates the mixture into three spots on a silica gel TLC plate. Considering the functional groups present, predict which compounds would have the smallest and largest Rf values. Briefly justify your answer. Temperature (°C)
