(b)
Interpretation:
The product of the dehydration of the aldol product has to be drawn.
Concept introduction:
Aldol reaction is an addition reaction of aldehydes and ketones. Aldol reaction is a reversible reaction and occurs in the presence of a strong base like sodium hydroxide. One molecule (aldehyde or ketone) acts a nucleophile and attacks the electrophilic carbon center of the other molecule to give the addition product. The product is named
