Vedclass · Answer

(D) The given reaction is an intramolecular aldol condensation. $1$. The base $(KOH)$ abstracts an $\alpha$-hydrogen from the ketone group to form an enolate. $2$. This enolate attacks the carbonyl carbon of the aldehyde group,forming a cyclic $\beta$-hydroxy ketone. $3$. Subsequent dehydration (catalyzed by $H^+, \Delta$) leads to the formation of an $\alpha,\beta$-unsaturated ketone. $4$. The resulting product is a spiro-compound where a cyclohexenone ring is fused to a cyclohexane ring.

The major product $(P)$ in the following reaction is :
