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

Tardigrade Admin · Accepted Answer

Statement (d) is false. Due to delocalisation of π bare prime s, benzene neither undergoes oxidation nor it gives test for unsaturation, i.e., Baeyer's reagent test and decolourisation of Br 2 solution

Q. Which of the following statements is/are correct?

The reductive and oxidative ozonolyses of $m$ - and $p$ -xylenes give the same product

The reductive ozonolysis of o-xylene $(1, 2$ -diamethyl benzenr) gives glyoxal+methylglyoxal+ dimethyl glyoxal in $3 : 2 : 1$ ratio

The ozonolysis of $o$ -xylene establishes the Kekule's structure of benzene and also proves the existence of resonance in benzene

The oxidation of benzene with acidic $K M n O_{4}$ gives $3 m o l$ oxalic acid

Statement (d) is false. Due to delocalisation of $π \overset{e}{ˉ}^{'}$ s, benzene neither undergoes oxidation nor it gives test for unsaturation, i.e., Baeyer's reagent test and decolourisation of $B r_{2}$ solution
