Question

Which of the following statements is/are correct?

• A. The reductive and oxidative ozonolyses of $m$ - and $p$-xylenes give the same product
• B. The reductive ozonolysis of o-xylene $(1,2$-diamethyl benzenr) 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 1

Answer: (A), (B), (C)

Statement (d) is false. Due to delocalisation of $\pi \bar{e}^{\prime}$ s, benzene neither undergoes oxidation nor it gives test for unsaturation, i.e., Baeyer's reagent test and decolourisation of $Br _2$ solution
