Identify A in the given chemical reaction.

(A)(see structure)
(B)(see structure)
✓ Correct
(C)(see structure)
(D)(see structure)

Answer: (B)

Solution

The reaction involves ozonolysis of a cyclic alkene followed by reductive workup. The starting material appears to be a bicyclic compound with a double bond. Ozonolysis cleaves the double bond and forms carbonyl groups. The product A shown in option (B) is consistent with ozonolysis of a tetralin-like structure, forming an aldehyde on the ring. The correct answer is (B).
