In which one of the following sets all species show disproportionation reaction?

Question

Canvas Classes · Accepted Answer

Check each set for all species being capable of disproportionation:

Set (1): , , , 
- : Cl =  (max) → cannot disproportionate ✗
- : Mn =  (max) → cannot disproportionate ✗
- : no positive OS → cannot disproportionate ✗

Set (2): , , , 
- : Mn =  → disproportionates to  (+7) and  (+4) ✓
- : Cl =  → disproportionates to  and  ✓
- : Cl =  → disproportionates in alkaline medium ✓
- : Mn =  → disproportionates to  and  ✓
All four can disproportionate ✓

Set (3) and (4): Contain  (Mn = , max) or  (Cr
