Answer 1

Answer:

IUPAC name is tris ethylenediamine nickel 2 chloride

Answer 2

The correct IUPAC name of [Ni(en)3]Cl2 is Tris (ethylene diamine) nickel(II) chloride.

- There are two chloride ions outside the coordination sphere.

- There are 3 ethylene diamine groups attached to nickel inside the coordination sphere, hence the prefix tris- is used.

- As ethylene diamine group is neutral, so the oxidation no of nickel in this compound is 2.

- Thus the name becomes Tris-(ethylenediamine) nickel(II) chloride.
