can you help with number 5 3. Use the eutectic diagram on the following page for the following questions.(a) What is the theoretical melting point for a mixture containing 80% by mole of A?(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?**Diagram Explanation:**- The diagram is a phase diagram showing the relationship between temperature (in °C) and mole fraction (Xₐ) of component A.- The temperature ranges from 130°C to 138°C.- The mole fraction (Xₐ) ranges from 0.00 to 1.00.- The graph shows a curve with a minimum point, indicating the eutectic point.4. Why must the spot be applied to the TLC plate above the level of development solvent?5. 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.
