The correct name for the complex ion [Co(NH₃)₅Cl]^2- is

Accepted Answer

The correct name for the complex ion [Co(NH₃)₅Cl]²⁺ is pentamminechlorocobalt(III). The name of a complex ion is derived from the names of the ligands and the metal ion. The ligands are named first, in alphabetical order, followed by the name of the metal ion. The name of the metal ion is modified to indicate its oxidation state. In this case, the metal ion is cobalt and its oxidation state is +3, so the name of the metal ion is cobalt(III).

Question 13

Question 16

What is the coordination number for copper in the compound K₂[CuCl₄]?

Accepted Answer

The coordination number is the number of ligand atoms that are bonded to the central metal atom. In K2[CuCl4], copper is coordinated to four chloride ions, giving it a coordination number of 4.

Question 17

What is the coordination number of the metal atom in the complex ion in K[Pt(NH₃)Cl₅]?

Accepted Answer

The coordination number of a metal atom is the number of ligands that are bonded to it. In the complex ion [Pt(NH3)Cl5]-, the platinum atom is bonded to five chloride ions and one ammonia molecule. Therefore, the coordination number of the platinum atom is 6.

Question 18

The correct name for K₂[CuCl₄] is

Accepted Answer

The name includes the prefix "tetra" indicating the presence of 4 chloride ions, and the suffix "-cuprate(II)" indicating the presence of copper in the +2 oxidation state. The name also includes the cation "potassium" which is written twice as it is a polyatomic ion in this compound.

Question 19

For the coordination compound [Zn(NH₃)₄]Cl₂, identify, in order, the charge on the complex ion, the coordination number of the metal, and the number of counter ions present.

Accepted Answer
