Which of the following statements is/are correct?

Options

A. The reductive and oxidative ozonolysis of m-and p-xylenes give the same product
B. The reductive ozonolysis of o-xylene (1,2-dimethyl benzene) gives glyoxal + methylglyoxal + dimethyl glyoxal in 3 : 2 : 1 ratio.
C. The ozonolysis of o-xylene establishes the Kekule’s structure of benzene and also proves the existence of resonance in benzene
D. The oxidation of benzene with acidic `KMnO_(4)` gives 3 mol oxalic acid.

Answer

A, B, C

Explanation

Due to delocalisation of `pibar(e)s`, benzene neither undergoes oxidation nor it gives test for unsaturation, ie, Bayer.s reagent test and decolourisation of `Br_(2)` solution.
