Vedclass · Answer

(A) The reaction sequence involves the conversion of an ester $(CH_3COOCH_3)$ to an aldehyde $(CH_3CHO)$ and vice versa.$1$. For the conversion of ester to aldehyde $(P)$,$DIBAL-H$ (Diisobutylaluminium hydride) is the standard reagent used at low temperature $(-78^{\circ}C)$ followed by hydrolysis $(H_2O)$.$2$. For the conversion of aldehyde to ester $(Q)$,the Tishchenko reaction is used. The Tishchenko reaction involves the disproportionation of an aldehyde to an ester in the presence of an alkoxide catalyst,such as aluminium isopropoxide,$Al(OCH(CH_3)_2)_3$.

Identify the reagents $P$ and $Q$ in the following reaction sequence:
