Vedclass · Answer

(A) For $(P)$: Cyclohexene undergoes ozonolysis to give hexanedial,followed by intramolecular aldol condensation to form cyclohex$-1-$enecarbaldehyde. Protection of the aldehyde with ethylene glycol,hydroboration-oxidation,deprotection,and reduction with $NaBH_4$ yields $(3)$.For $(Q)$: $1-$Methylcyclohexene undergoes ozonolysis,aldol condensation,protection,hydroboration-oxidation,deprotection,and reduction to yield $(5)$.For $(R)$: $3-$Methylcyclopent$-2-$enone is protected,subjected to oxymercuration-demercuration,deprotected,and reduced to yield $(4)$.For $(S)$: $3-$Methylcyclopent$-2-$enone is protected,subjected to hydroboration-oxidation,deprotected,and reduced to yield $(1)$.Thus,the correct matching is $P-3, Q-5, R-4, S-1$.

List-$I$ contains various reaction sequences and List-$II$ contains the possible products. Match each entry in List-$I$ with the appropriate entry in List-$II$ and choose the correct option.
