Chemistry - Coordination Chemistry Question with Solution | TestHub
Match the complexes in Column I with their properties listed in Column II. Indicate your answer by darkening the appropriate bubbles of the matrix given in the ORS.
List - I | List - II |
|---|---|
(A) | (P) Geometrical isomers |
(B) | (Q) Paramagnetic |
(C) | (R) Diamagnetic |
(D) | (S) Metal ion with 2+ oxidation state |
Options:
Answer:
Solution:
(A) : Cobalt is in the +2 oxidation state (, high spin), making it paramagnetic (Q, S). As an octahedral complex, it shows cis-trans geometrical isomerism (P).
(B) : Platinum is in the +2 oxidation state (S). This is a square planar complex, which is always diamagnetic (R) and exhibits cis-trans geometrical isomerism (P).
(C) : Cobalt is in the +2 oxidation state (S). In this octahedral field, it is high spin and thus paramagnetic (Q).
(D) : Nickel is in the +2 oxidation state (S). As a octahedral complex with weak field ligands, it has two unpaired electrons and is paramagnetic (Q).
