Solution:

All aldehydes can made to undergo the Cannizzaro reaction by treatment with aluminium ethoxide. Under these conditions, the acid and alcohol are combined to form an ester. The reaction is called Tischenko reaction.

$CH _{3} CHO + CH _{3} CHO$ $\stackrel{ Al \left( OC _{2} H _{5}\right)_{3}}{\longrightarrow }\left[ CH _{3} COOH + CH _{3} CH _{2} OH \right] \rightarrow CH _{3} COOCH _{2} CH _{3}$
