Name the reagents used in the following reactions:
i) (the carbonyl reduction shown in the figure)
ii) C₆H₅–CH₂–CH₃ → C₆H₅–COO⁻K⁺
Structure Reaction (i)
Reaction (i)

Solution

(i) The displayed carbonyl → alcohol step uses \textbf{NaBH} (or LiAlH) — hydride reduction.
(ii) Side-chain oxidation to the benzoate needs \textbf{alkaline KMnO} (then the product is the potassium salt shown).
