Give the IUPAC names of the following compound `[Co(NH_3)_5Cl]Cl_2`

Explanation

To determine the IUPAC name of the compound \([Co(NH_3)_5Cl]Cl_2\), we will follow these steps:

### Step 1: Determine the Oxidation State of Cobalt
Let \(X\) be the oxidation state of cobalt. The ammonia (\(NH_3\)) is a neutral ligand, contributing a charge of 0. The chloride ion (\(Cl^-\)) is an anionic ligand, contributing a charge of -1. The compound has two chloride ions outside the coordination sphere.

The overall charge of the coordination sphere must balance with the charges from the ions outside. The coordination sphere is neutral, and the two chloride ions contribute a total charge of -2.

Setting up the equation:
