Step 1: LiAlH₄ reduces hexanoic acid (CH₃(CH₂)₄COOH) to hexan-1-ol (CH₃(CH₂)₅OH). Step 2: Clemmensen-like reduction (not direct) or dehydration followed by hydrogenation could work, but Wolff-Kishner on the derived ketone fits PDF scope.

Reaction: C₅H₁₂ + 8O₂ → 5CO₂ + 6H₂O. Moles of C₅H₁₂ = 11.2/72 ≈ 0.1556 mol. 1 mol produces 5 mol CO₂; 0.1556 mol produces 0.7778 mol. Volume = 0.7778 × 22.4 ≈ 17.42 L.
