Match the statements given in Column-I with the oxidation states given in Column-II
List - I | List - II |
|---|---|
(A) Oxidation state of Mn in is | (P) + 2 |
(B) Most stable oxidation state of Mn is | (Q) +3 |
(C) Most stable oxidation state of Mn in Oxidation state of Mn in oxides is | (R) +4 |
(D) Characteristic oxidation state of Lanthanoids is | (S) +5 |
| (T) +7 |
Options:
Answer:
C
Solution:
Oxidation state of Mn in ManganeseO is +2 → (A → R).
Most stable oxidation state of Mn is +2 due to half-filled stability → (B → P).
Highest/stable oxidation state of Mn in oxides is +7 (as in permanganate) → (C → T).
Oxidation state of Mn in common oxides varies, typically +3/+4 → (D → Q).
Lanthanoids generally show +3 oxidation state as the characteristic state.
Hence, final matching is A→R, B→P, C→T, D→Q.
