Question

`"Ethanal" overset(Al(OC_(2)H_(5))_(3))rarr X overset(C_(2)H_(5)ONa)rarr Y`
In the above reaction X and Y are
A. `CH_(3) - COOH, CH_(3)COOC_(2)H_(5)`
B. `CH_(3)COOC_(2)H_(5), CH_(3)COCH_(2)COOC_(2)H_(5)`
C. `CH_(3)COOH, CH_(3)COCH_(3)`
D. None of the above

Answer 1

Correct Answer - B
`underset"Ethanal"(2CH_(3)CHO) underset("Tischenko reaction")overset(Al(OC_(2)H_(5))_(3))rarr underset((X))(CH_(3) COOC_(2)H_(5)) overset(+C_(2)H_(5)ONa)rarr underset("Ethyl acetoacetate (Y)")(CH_(3) - overset(O)overset(||)(C) - CH_(2) - overset(O)overset(||)(C) - OC_(2)H_(5))`
