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...
