AlCl3 AICI:
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
