Isomerism In Coordination Compounds

Step 1: Concept
Linkage isomerism occurs in ligands that can bond to metal through different atoms.
Step 2: Analysis
can bond through nitrogen or oxygen.
Step 3: Conclusion
It forms isomers like pentaaminenitro and pentaaminenitrito complexes.
Final Answer: (A)

Step 1: Formula
According to Ampere's circuital law, .
Step 2: Internal Point
For any point inside the pipe ( ), the current enclosed by the Amperian loop is zero.
Step 3: Calculation
.
Final Answer: (c)

Step 1: Understanding the Concept:
hybridisation gives outer orbital (high spin) octahedral complexes. Weak field ligands (F ) cause this.

Step 2: Detailed Explanation:
(A) Co in [CoF ] : F is weak field ligand, so electrons do not pair, hybridisation = (outer orbital).
(B) [Co(NH ) ] : NH is strong field, hybridisation = (inner orbital).
(C) [Fe(CN) ] : CN is strong field, hybridisation = .
(D) [Cr(NH ) ] : NH is strong field for Cr , hybridisation = .

Step 3: Final Answer:
