Which is the most polar of each solvent pair? Toluene or Ethyl Acetate? Methanol or DCM (dichloromethane)? Benzene or Phenol? Benzoic acid or Cyclohexane?
In the mechanism for formation of acetylsalicylic acid via reaction of salicylic acid with acetic anhydride, phosphoric acid acts as a catalyst by O cleaving an acetyl group from acetic anhydride via protonation of the bridging oxygen O neutralizing the hydroxide ion side product protonating the carbonyl oxygen in the acetic anhydride protonating the phenolic oxygen of salicylic acid Question 10 (3 points) What would be the predicted major product from the thermodynamically controlled dehydration of the following material OH

Check Your Learning Ethanol and acetic acid react and form water and ethyl acetate,the solvent responsible for the odor of some nail polish removers. 2 15 When 1 mol each of C2H5OH and CH3CO2H are allowed to react in 1 L of the solvent dioxane, equilibrium is established when mol of each of the reactants remains. Calculate the equilibrium constant for the reaction. (Note: Water is not a solvent in this reaction.)
only question # 2
a. using anhydrous ether b. not rinsing glassware with acetone before the experiment c. using magnesium filings instead of "chunk" magnesium d. initiating the reaction in a test tube e. using an ammonium chloride/hydrochloric acid mixture to acidity the reaction mixture instead of using concentrated sulfuric acid. 2. Give the products of the reaction of methylmagnesium chloride with a. acetaldehyde me mac b. acetone c. ethyl acetate (1 equivalent per Grignard) d. ethyl acetate (2 equivalents...
organic chemistry. why is CH3ONa not used in the claisen
condensation of ethyl acetate
12. Why is CH3ONa not used in the Claisen condensation of ethyl acetate? a. CH30 is a weaker base than the CH3CH20-which is used. b. CH3O- Nat is more difficult to prepare than CH3CH2O Nat. c. CH3O- would abstract a proton from the ethyl group of the ester. d. Use of CH,O- Na would result in transesterification e. CH,O- Na can be used as well as...
