The List-II contains products obtained from the reaction of compounds in List-I with followed by cyclization (via more stable enolate) in the presence of aqueous NaOH. Match each entry in List-I with appropriate entry in List-II and choose the correct option.
| List-I | List-II | ||
|---|---|---|---|
| (P) |  | (1) |  |
| (Q) |  | (2) |  |
| (R) |  | (3) |  |
| (S) |  | (4) |  |
| (5) |  |
- (A)
- (B)
- (C)✓ Correct
- (D)
Answer: (C)
Solution
Ozonolysis of the alkenes in List-I followed by reductive workup () gives dicarbonyl compounds. These undergo intramolecular aldol condensation in aqueous NaOH via the more stable enolate to form cyclic products.
