Draw structural formulas for an aldehyde or ketone and alkyl (or aryl) bromide that could be used in a Grignard synthesis of the alcohol shown 111 CH3 OH CH3CHCH2CHCH3 . You do not have to consider stereochemistry If there is more than one combination, draw only one. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate multiple reactants usıng the 111 sign from the drop-down menu.

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.
