Vedclass · Answer

(A) The given reaction is an intramolecular aldol condensation of $o$-phenylenediacetaldehyde. $1$. The base $(OH^-)$ abstracts an $\alpha$-hydrogen from one of the aldehyde groups to form an enolate ion. $2$. This enolate ion performs a nucleophilic attack on the carbonyl carbon of the other aldehyde group,leading to the formation of a cyclic $\beta$-hydroxy aldehyde. $3$. Upon heating in the presence of an acid or base (dehydration),the $\beta$-hydroxy aldehyde undergoes elimination of a water molecule to form an $\alpha,\beta$-unsaturated aldehyde. $4$. The final product is $2$-formyl$-1,2,3,4-$tetrahydronaphthalene.
