Ester having alpha-hydrogen on treatement with a strong base eg. C_(2)

1.	Ester having alpha-hydrogen on treatement with a strong base eg. C_(2)H_(5)Ona undergoes self condensation to produce beta-keto esters. This is called claisen condensation C_(6)H_(5)-underset(O)underset(\|\|)(C)-OC_(2)H_(5)+CH_(3)-underset(O)underset(\|\|)(C)-OC_(2)H_(5) overset((1) C_(2)H_(5)overset(Theta)(O)Na^(o+))underset((2) H^(o+))to
Answer» `C_(6)H_(5)-underset(O)underset(\|\|)(C)-CH_(2)-underset(O)underset(\|\|)(C)-OC_(2)H_(5)+C_(2)H_(5)OH` `C_(6)H_(5)-underset(O)underset(\|\|)(C)-O-CH_(2)-underset(O)underset(\|\|)(C)-OC_(2)H_(5)+C_(2)H_(5)OH` `C_(6)H_(5)-underset(O)underset(\|\|)(C)-O-underset(O)underset(\|\|)(C)-OC_(2)H_(5)+C_(2)H_(5)OH` NONE of these Solution :
