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.
List-I (P) (see reaction scheme) (Q) (see reaction scheme) (R) (see reaction scheme) (S) (see reaction scheme)
List-II (1) (see structure) (2) (see structure) (3) (see structure) (4) (see structure) (5) (see structure)PQRS12345
(A)P→3, Q→5, R→4, S→1✓ Correct
(B)P→3, Q→2, R→4, S→1
(C)P→3, Q→5, R→1, S→4
(D)P→5, Q→2, R→4, S→1
Answer: (A)
Solution
Each reaction sequence in List-I leads to a specific product through the given reagents and conditions. (P) involves ozonolysis, aldol condensation, protection/deprotection, and hydroboration-oxidation leading to product (3). (Q) involves a multi-step transformation leading to product (5). (R) produces product (4). (S) gives product (1). The matching is based on mechanistic analysis of each reaction sequence.
