Product (B) of the above reaction is:
Open in App
Solution
The correct option is C
First reaction is retro aldol reaction. It is a reverse of aldol reaction.
Initially the strong base will abstract the acidic proton from the OH and forms a keto group which leads to C−C bond breakage to form carbanion followed by proton abstraction.
Formed acetaldehyde undergoes cross aldol reaction with formaldehyde. The substrate are in 3:1 (HCHO:CH3CHO) ratio which will induce the mutiple enolate formation and corresponding aldol formations.
Hence,
