Question
Identify reagents that can be used to convert toluene into benzoic acid.
Select answer from the options below:
- CH₃COOH
- Na₂Cr₂O₇, H₂SO₄, H₂O
- excess NaOH
- H₃O⁺
Solution
To convert toluene (C₇H₈) into benzoic acid (C₇H₆O₂), we need to perform an oxidation reaction. The most effective reagents from the given choices are typically oxidizing agents.
Analyzing the Options
- CH₃COOH (Acetic Acid): This is not an oxidizing agent and will not convert toluene to benzoic acid.
- Na₂Cr₂O₇, H₂SO₄, H₂O: Sodium dichromate (Na₂Cr₂O₇) in sulfuric acid (H₂SO₄) is a strong oxidizing agent that can oxidize toluene to benzoic acid.
- Excess NaOH: Sodium hydroxide is a strong base but is not typically used for this type of oxidation.
- H₃O⁺: Hydronium ion is an acid and does not oxidize toluene.
Conclusion
The most suitable choice from the options listed for converting toluene to benzoic acid is Na₂Cr₂O₇, H₂SO₄, H₂O.
