-
A. None of these
-
B. +2
-
C. Both A and B
-
D. 4
Explanation
The complex [Cu(en)2]^+² contains 2 ethylenediamine (en) ligands.
Each en is a bidentate ligand, donating 2 lone pairs, so:
2 ligands × 2 = 4 coordinate bonds → Coordination number = 4
-
A. 1
-
B. 4
-
C. None of these
-
D. 2
Explanation
The coordination number of a metal atom in a complex is the number of ligands directly attached to it.
In [PtCl(NO)(NH₃)₂], the ligands are:
Total number of ligands = 1 + 1 + 2 = 4
The coordination number of Pt is 4, since it is bonded to 4 ligands.
