This question concerns the electrocyclic ring closure of the non-conjugated diene 16 to give the product 17 (shown below). Answer BOTH parts (i) and (ii). 16 17 (i) Provide a full "curly arrow" mechanism for the formation of the product 17 and state the number of electrons participating in the pericyclic reaction. ( 6 marks) (ii) Give the relative stereochemistry of the hydrogen atoms in bold observed for the product 17. Make sure to include a diagram that gives the frontier orbital description of the ring closure to help justify your
