QJEEM24Ch386e: JEE Main 2024 Chemistry - Class 12 JEEM24Ch386e Solution: Given below are two statements: Statement I : solid undergoes…

Given below are two statements:

Statement I : S8\mathrm{S}_8 solid undergoes disproportionation reaction under alkaline conditions to form S2−\mathrm{S}^{2-} and S2O32−\mathrm{S}_2 \mathrm{O}_3{ }^{2-} .

Statement II : ClO4−\mathrm{ClO}_4^{-} can undergo disproportionation reaction under acidic condition.

In the light of the above statements, choose the most appropriate answer from the options given below :

Multiple Choice Options

  • A Statement I is correct but statement II is incorrect
  • B Both statement I and statement II are incorrect
  • C Statement I is incorrect but statement II is correct
  • D Both statement I and statement II are correct

Step-by-Step Verified Solution

S1:S8+12OH⊖→4 S2−+2 S2O32−+6H2O\mathrm{S}_1: \mathrm{S}_8+12 \mathrm{OH}^{\ominus} \rightarrow 4 \mathrm{~S}^{2-}+2 \mathrm{~S}_2 \mathrm{O}_3^{2-}+6 \mathrm{H}_2 \mathrm{O}

S2:ClO4⊖\mathrm{S}_2: \mathrm{ClO}_4^{\ominus} cannot undergo disproportionation reaction as chlorine is present in it's highest oxidation state.
