I recently came across a question where naphthalene undergoes oxidation with sodium dichromate in presence of sulfuric acid. The given options were benzoic acid, phthalic acid, decalin, and tetralin.
I assumed the reaction to be similar to that of the reaction between potassium permanganate under acidic conditions, yielding phthalic acid. This reaction was described in Oxidation of naphthalene with KMnO4.
Could anyone please clarify the reaction, whether my assumption is correct, and explain the mechanism?
