structures. Explain why the major product(s) are formed over the minor product(s) using the Draw the major and product and the complete mechanism for all products with all resonance mechanism/resonance structures of the major and minor products in your explanation. HONO2 H2SO4

#1 (a). Provide the expected product for the following reaction of A to B by indicating what the product is after step 1 (call this "81") and after step 2 (call this product "B2"). Give a complete mechanism for the transformation of compound A into compound B showing all intermediates, resonance structures, stereochemistry and electron movements 1. Et-MgBr 2. Me-Br B #1 (b). Compound A can be prepared in one step from an alkene starting material. Provide the structure a and the reaction conditions required to convert it to compound A The starting alkene
