This reaction takes place between two molecules of esters (same or different). One ester should have atleast one `alpha`-hydrogen atom which behaves as a reagent. The reaction is catalyzed by strong bas elike `C_(2)H_(5)barONa^(+)` in presence of `C_(2)H_(5)OH`. The product of this reaction is `beta`-ketoster:
Which of the following esters will undergo Claisen condensation to form acetoacetic ester ?
A. `CH_(3)COOC_(2)H_(5)`
B. `C_(6)H_(5)COOC_(2)H_(5)`
C. `HCOOC_(2)H_(5)`
D. None of these
