Mark the reaction among the following that does not give benzoic acid as the major product:

1. Ethylbenzene (and any alkyl benzene with benzylic hydrogen) is oxidized by ${\text{KMnO}}_4$ to benzoic acid.2. Tollen's reagent oxidizes aldehydes to the corresponding carboxylic acid salt, which gives benzoic acid upon acidification.3. Benzyl alcohol is oxidized by ${\text{K}}_2{\text{Cr}}_2{\text{O}}_7$ to benzoic acid.4. Chlorobenzene with $\text{aq. NaOH}$ (Dow's Process condition or standard substitution) yields Phenol, not benzoic acid.
