Match the List :-
List - I (Properties) | List - II (Compound) |
|---|---|
(P) Paramagnetic coloured | Na₃[CrF₆](aq)
|
(Q) Diamagnetic coloured | K₂Cr₂O₇ (s) |
(R) Paramagnetic colourless | [Zn(CN)₄]²⁻(aq)
|
(S) Diamagnetic colourless | VOSO₄(aq) |
Select correct code :
Options:
Answer:
D
Solution:
Paramagnetic vs Diamagnetic: Count unpaired electrons
Colour: d-d transition → coloured if partially filled d-orbitals, colourless if d⁰ or d¹⁰
Paramagnetic + Colourless: d⁰ complex (O₂ exception)
Diamagnetic + Coloured: usually d¹⁰ complex with charge transfer
