Draw curved arrows for each step of the following mechanisms. Note: you will have to explicitly redraw out the molecules yourself to show bonds to hydrogens on heteroatoms that are breaking. Remember to draw in all lone pairs that are being used as electron sources for curved arrows – curved arrows must always come from lone pairs or bonds! но он но но он но но Х.но он он X - но он Х ня_s"-оон 10 но он НО H2O...

Problem 5 Use curved arrows to show mechanisms for both of the following reactions; the second reaction produces a single product. Predict the structure of product A using your mechanism. In order to explain the regioselectivity in the formation of product A, include a detailed resonance analysis of the mechanism (i.e. show all resonance forms of the carbocation that contribute to the selectivity). Please also explain the observed selectivity in a few sentences. i-PrSNa HNO3 H2SO4
