Section A: Apply your knowledge 1. Decide whether the following nucleophiles would react with a ketone, aldehyde, or both and draw the corresponding product(s). If a reaction seems unfavorable explain why/how a product can still be obtained. H₂O Or MeOH Or O HO OH Or H2N—Ph Or H3C CH3 Or 1.1 HO HN—CH3 Or

Answer all three parts plz. You are starting with three aryl bromides. They undergo a typical grignard reaction with magnesium metal and anhydrous ether (diethyl ether). Dry ice is then added to it and it is then cooled. Draw and label the names of the aryl carboxylic acids that will form for each. Part a) 4-bromonitrobenzene Part b) 4-bromotoluene Part c) 2-bromotoluene
