Question

Given below are two statements:

Statement I:  solid undergoes disproportionation reaction under alkaline conditions to form  and .
Statement II:  can undergo disproportionation reaction under acidic condition.

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

Step 1 — Evaluate Statement I:

in alkaline medium:

- S in : OS = 
- S in : OS =  (reduced)
- S in : average OS =  (oxidised)

Same element (S) simultaneously oxidised and reduced → Disproportionation ✓
Statement I is CORRECT ✓

Step 2 — Evaluate Statement II:

(perchlorate): Cl is in its highest oxidation state (+7). It cannot be further oxidised → cannot undergo disproportionation.

can only act as an oxidising agent (be reduced), not disproportionate.
Statement II is INCORRECT ✗
