During decomposition of it undergoes:

During decomposition of \( \boldsymbol{H}_{2} \boldsymbol{O}_{2}, \) it undergoes:

  • A. oxidation
  • B. reduction
  • C. redox reaction
  • D. disproportionation

Step-by-step solution

Hydrogen peroxide decomposes to water and oxygen. In H2O2, oxygen has oxidation state -1. It is reduced to -2 in H2O and oxidized to 0 in O2, so it undergoes disproportionation, a type of redox reaction where the same element is both oxidized and reduced.
