Easy MCQ +4 / -1 PYQ · JEE Mains 2021

Which of the following equation depicts the oxidizing nature of H2O2?

  1. A $C{l_2} + {H_2}{O_2} \to 2HCl + {O_2}$
  2. B $KI{O_4} + {H_2}{O_2} \to KI{O_3} + {H_2}O + {O_2}$
  3. C $2{I^ - } + {H_2}{O_2} + 2{H^ + } \to {I_2} + 2{H_2}O$ Correct answer
  4. D ${I_2} + {H_2}{O_2} + 2O{H^ - } \to 2{I^ - } + 2{H_2}O + {O_2}$

Solution

$2{I^ - } + {H_2}{O_2} + 2{H^ + } \to {I_2} + 2{H_2}O$ <br><br>Oxygen reduces from –1 to –2. <br><br>So, its reduction will takes place. Hence it will behave as oxidising agent or it shows oxidising nature. <br><br>While in other option it change from (–1) to 0.
