Vedclass · Answer

(B) The given compound is $CH_3COCH_2CH_2CH_2CH_2CHO$ (heptane$-2,6-$dione derivative or similar keto-aldehyde). Intramolecular aldol condensation occurs between the $\alpha$-hydrogen of the ketone and the carbonyl carbon of the aldehyde. The enolate formed at the $\alpha$-position of the ketone attacks the aldehyde carbonyl carbon to form a five-membered ring. Dehydration of the resulting $\beta$-hydroxy ketone under heating $( \Delta )$ yields the conjugated enone. The major product is $1-	ext{acetylcyclopentene}$.

When the compound $CH_3COCH_2CH_2CH_2CH_2CHO$ undergoes intramolecular aldol condensation,the major product formed is $:$
