Number one please!
-pentanol Dilute the combined aqueous layers and washes with water, neutralize the necessary, and flush it down the drain with excess water. Place the ether distillte container for nonhalogenated organic solvents. Spread the calcium chlorid the the drying tube and the sodium sulfate on a tray in the hood, and then place then the container for nonhazardous solids after the volatiles have evaporated the from 1. Arrange the following compounds in order of increasing reactivity toward attack of a Grignard reagent at the carbonyl carbon atom: methyl benzoate. benzoic acid, benzaldehyde, and benzophenone. Explain the basis for your decision, making use of mechanisms where needed. 2. What is (are) the product(s) of reaction of each of the carbonyl-containing com- pounds in Exercise 1 with excess Grignard reagent, RMgBr? 3. How might primary, secondary, and tertiary alcohols be prepared from a Grignard reagent and a suitable carbonyl-containing compound? Write chemi- cal reactions for these preparations using any starting materials you wish; indi- cate stoichiometry where important. 4. Why is it unwise to begin addition of the solution of methyl benzoate to the Grignard reagent before the latter has cooled to room temperature and then been placed in an ice-water bath? 5. Why should anhydrous rather than solvent-grade diethyl ether be used to pre pare the solution of methyl benzoate that is added to the Grignard reagent? 6. What is the solid that forms during the addition of the ester to the Grignard reagen 7. Why is it necessary to acidify the mixture obtained after the reaction of methy t? benzoate with phenylmagnesium bromide? whole or in part rved.
