MCQ
Given below are two statements :
Statement I: $S _8$ solid undergoes disproportionation reaction under alkaline conditions to form $S ^{2-}$ and $S _2 O _3^{2-}$
Statement II: $ClO _4^{-}$can undergo disproportionation reaction under acidic condition.
In the light of the above statements, choose the most appropriate answer from the options given below :
  • Statement I is correct but statement II is incorrect.
  • B
    Statement I is incorrect but statement II is correct
  • C
    Both statement I and statement II are incorrect
  • D
    Both statement I and statement II are correct

Answer

Correct option: A.
Statement I is correct but statement II is incorrect.
(A)
$
S_1: S_8+12 OH^{\ominus} \rightarrow 4 S^{2-}+2 S_2 O_3^{2-}+6 H_2 O
$$S _2: ClO _4^{\ominus}$ cannot undergo disproportionation reaction as chlorine is present in it's highest oxidation state.
