NEET Chemistry Coordination Number Assertion Reason Question
Assertion (A): The coordination number of the central atom in [Fe(CN)6]4- is 6.
Reason (R): The coordination number is determined by the number of sigma bonds formed between the ligands and the central atom.
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 defined by the number of sigma bonds formed between ligands and the central atom, as seen in the example [Fe(CN)6]4- where the coordination number is 6 due to six sigma bonds.
