Self-condensation of two moles of ethyl acetate in presence of sodium ethoxide yields
ethyl butyrate
acetoacetic ester
methyl acetoacetate
methyl acetoacetate
B.
acetoacetic ester
On condensation of two moles of ethyl acetate in presence of sodium ethoxide, gives ethyl acetoacetate (ester). This condensation is an example of claisen condensation because it is possible in that ester which has an alpha hydrogen atom.
