NEET Chemistry Coordination Number Assertion Reason Question
Assertion (A): The coordination number of a central metal atom is determined by the number of ligand donor atoms to which the metal is directly bonded.
Reason (R): In the complex [Fe(CN)6]4-, the coordination number of iron is 4 because it can only accommodate four cyanide ions.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
The coordination number is determined by the number of ligand donor atoms directly bonded to the metal. In [Fe(CN)6]4-, the coordination number of iron is 6 because there are six cyanide ions bonded to it.
