0
Step-by-step solution
In an aldol condensation, an enolate ion reacts with a carbonyl compound in the presence of acid/base catalyst to form a β-hydroxy aldehyde or β-hydroxy ketone, followed by dehydration to give a conjugated enone. It is a useful carbon-carbon bond-forming reaction.
As there are 2 pi bonds in the major product(P), the number of pi electrons will be equal to 4.
