For question 3c below, which of the puzzle pieces makes the best sequence for each synthesis? You must solve the syntheses with the puzzle pieces provide and nothing else. One piece can only be used once

8) Show how the following conversions might be accomplished, including all reagents and intermediates. Br Y. OH

1.Draw a structural formula for the more stable carbocation intermediate formed in the reaction shown. 2.Draw a structural formula for the major organic product of the reaction shown.

1A. Explain why solvents such as anhydrous diethyl ether or anhydrous tetrahydrofuran (THF) are not reactive with Grignard reagents. 1B. Draw the first step of the reaction mechanism when the Grignard reagent attacks benzophenone before the alkoxide is protonated to form the alcohol. In the mechanism, identify the partially positive and partially negative atoms in the reactants. Explain why these atoms have a partial charge. 1C. Write the mechanism for the reaction of phenyl magnesium bromide with 1) water and 2) acetone.
