Q. Acetophenone when reacted with a base, $C_2H_5ONa$, yields a stable compound which has the structure
Aldehydes Ketones and Carboxylic Acids
Solution:
The first step is a simple condensation reaction. The last step is an example of $ElcB$ mechanism and the leaving group is hydroxide, which is unusual. Still this step manages to take place owing to the stability incorporated there in the product, which is a conjugated carbonyl compound.
