Question

IUPAC name of [CO(NH3)Cl]2+​

Answer 1

Explanation:

The name of the given complex is Pentaamminechlorocobalt (III) Chloride.

Since the chloride ion carries a charge of -1, therefore the cationic complex has an overall charge of +2, and therefore would be denoted by [Co(NH3)5Cl]2+. Now NH3 is a neutral ligand. Let the oxidation state of cobalt be x, therefore we will have

x - 1 = 2

x = 3

Thus the oxidation state of Cobalt will be +3.
