Question

If EAN of a central metal ion $X^{+2}$ in a complex is 34. and atomic number of $X$ is 28. The number of monodentate ligands present in complex are:

• A. 3
• B. 4
• C. 6
• D. 2

Answer 1

Answer: (B)

4

EAN=(Atomic Number)-(Charge)+2(No. of monodentate ligands)

$34=28-\left(2\right)+2\times$(No. of monodentate ligands)

$8=2\times$(No. of monodentate ligands)

$\therefore$No. of monodentate ligands $=4$
