What is total number of donor atoms in [ Co ( H ₂ O ) ( NH ₃ )₅ ] I ₃ ?

Options

Correct answer

C. 6

Step-by-step solution

In [ Co ( H ₂ O ) ( NH ₃ )₅ ] I ₃ , five ammonia molecules and one water molecule, that is, total six ligands are attached to cobalt ion. All these ligands are monodentate since each has only one donor atom. Therefore, there are six donor atoms in the complex.
