NEET Chemistry Coordination Number Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Coordination number of [Ni(CN)4]2– | (i) 4 |
| (b) Coordination number of [CoCl3(NH3)3] | (ii) 6 |
| (c) Coordination number of [Fe(CN)6]4– | (iii) 3 |
| (d) Coordination number of [Cu(NH3)2]2+ | (iv) 2 |
a-i, b-ii, c-iv, d-iii
a-i, b-ii, c-ii, d-iv
a-ii, b-i, c-ii, d-iv
a-i, b-iv, c-ii, d-iii
Correct Answer
Detailed Explanation
The coordination number of [Ni(CN)4]2– is 4, [CoCl3(NH3)3] has a coordination number of 6, [Fe(CN)6]4– also has a coordination number of 6, and [Cu(NH3)2]2+ has a coordination number of 2, based on the number of sigma bonds formed by the ligands with the central atom.
