Q. The coordination number of Cu in $\left\lbrack Cu\left( H_{2}O \right)_{4} \right\rbrack^{2 +}$ complex is
A) 2
B) 1
C) 3
D) 4
Explanation
(d)
The total number of monodentate ligands attached to the central metal is known as coordination number. Hence, in $\left\lbrack Cu\left( H_{2}O \right)_{4} \right\rbrack^{2 +}$ coordination number of Cu atoms is 4.
