Answer 1

Answer: tetra amine chlorido nitrito-o cobalt(3) chloride

Explanation:

Answer 2

The IUPAC name of [Co(NH3)4Cl(NO2)]Cl​ is Tetraamminechloridonitrito-N-cobalt (III) Chloride.

- Here, one chloride ion is outside the coordination sphere and one chloride ion, one nitrite ion and 4 amine groups are inside the coordination sphere.

- Here, the oxidation state of Cobalt is +3 as there are 3 ions with -1 charge attached to it.

- Arrange the name of ligands inside the coordination sphere in alphabetical order.

- Put the value of the oxidation state in parenthesis.

- Also, -N- is written to show that N atom of nitrite ion is attached to cobalt.

- Hence, the name becomes Tetraamminechloridonitrito-N-cobalt (III) Chloride.
