Vedclass · Answer

(A) $1$. The starting material contains one alkyne group and two alkene groups (one in a cyclopentene ring and one in a cyclohexene ring).$2$. The first step uses $H_2, Pd-BaSO_4$,and quinoline (Lindlar's catalyst),which selectively reduces the alkyne to a $cis$-alkene without affecting the other alkene groups.$3$. The second step uses dilute $KMnO_4$ at $273 \ K$ (Baeyer's reagent),which performs syn-dihydroxylation of all double bonds present in the molecule.$4$. The molecule has three double bonds: one newly formed $cis$-alkene from the alkyne and the two original cyclic alkenes.$5$. Each double bond undergoes dihydroxylation,adding two $-OH$ groups per double bond.$6$. Total $-OH$ groups $= 3 	imes 2 = 6$.

Total number of hydroxyl groups present in a molecule of the major product $P$ is. . . . . . . .
