Answer» Solution :a. b. C. d. It involves 1,4-addition followed by tautomerisation. e. f. g. h. `A implies PhCOCI` i. j. Perkin reaction: k. l. Reimer-Tiemann reaction: m. n. o. p. `(B) rArrunderset(("Pinacol) (Benzopinacol"))(Ph-underset(OH)underset(\|)overset(Ph)overset(\|)(C)-underset(OH)underset(\|)overset(Ph)overset(\|)(C)-Ph)` Q. Cross Cannizzaro reaction: (B) `implies HCOOK` R. Fridel-Crafts reaction: Acetylation `(ZnCI_(2)+HCI)` (Lewis acid). s. `SeO_(2)` oxidises active methylene group to carbonyl group. `[(A) implies PhCOCHO)]` t. `CH_(3)COOH+KCN rarr HCN+CN_(3)COOK`. The nucleophilic 1,4-addition takes place. u. v. Fries MIGRATION of isopropyl group: w. x. (A) `implies PhCOOK, (B) implies` y. z. Intermolecular Cannizzaro reaction:
