Question details

CHEM61041 Question 2 continued (b) Answer ALL parts (i) - (iii) Sulfate ion 5 forms a 1:1 host-guest complex in methanol with cation 6, with a binding constant of 313 M . Complexation of sulfate 5 to the dication 7 also gives a 1:1 host- guest complex, with a binding constant of 6.8 x 10M- da НН НН 6 OCH2Ph (i) Sketch a possible structure for the 1:1 complex of sulfate 5 with dication 7, and use it to explain why sulfate 5 complexes more strongly to dication 7 than to cation 6 Indicate on your structure two supramolecular interactions that support complex formation. (8 marks) (ii) Explaining your reasoning, would you expect the complexation of sulfate 5 by dication 7 to be stronger in water than in methanol? (2 marks) (iii) Use the binding constants above to calculate the effective molarity for the complexation of sulfate 5 to dication 7 (2 marks) Question 2 continued on next page

can anyone answer all the parts please. thank you.
