  1. Salicylic acid (ortho-hydroxybenzoic acid)
  2. Acetic acid
  3. Methanoic acid
  4. Benzoic acid
Show answer and solution

Correct answer: A. Salicylic acid (ortho-hydroxybenzoic acid)

**Kolbe-Schmitt:** PhONa + CO₂ (gaseous, 4-7 atm, 125 °C), then H⁺ → 2-hydroxybenzoic acid (salicylic acid). Industrial route to salicylic acid (precursor to aspirin = acetylsalicylic acid).
