Write the chemical formula of these coordination compounds

Write the chemical formula of these coordination compounds. formula name dicarbonyldichloromanganese(IV) bromide tetraamminedibromoplatinum(IV) bromide potassium aquapentachlorocobaltate(III)

The Correct Answer and Explanation is:

Here are the chemical formulas for the coordination compounds you mentioned:

1. Dicarbonyldichloromanganese(IV) bromide
   The name indicates that there are two carbonyl groups (CO), two chlorine (Cl) atoms, and one manganese ion in the +4 oxidation state (Mn4+), along with a bromide ion (Br−).
   The formula would be:
   Mn(CO)2Cl2BrExplanation:
   • The “dicarbonyl” part refers to two carbon monoxide (CO) ligands attached to the central metal, manganese.
   • “Dichloro” indicates two chloride ions (Cl−) bound to the metal.
   • The “bromide” ion is also a ligand and is present as Br−.
2. Tetraamminedibromoplatinum(IV) bromide
   This compound consists of a platinum ion (Pt4+) coordinated with four ammonia molecules (NH3), two bromine ions (Br−) attached to the platinum, and an additional bromide ion as a counterion.
   The formula is:
   [Pt(NH3)4Br2]BrExplanation:
   • “Tetraamine” indicates four ammonia molecules as ligands.
   • “Dibromo” specifies two bromine ions as ligands attached to platinum.
   • Platinum is in the +4 oxidation state, as indicated by the “(IV)” in the name.
   • The second bromide ion (Br−) is the counterion balancing the charge of the complex.
3. Potassium aquapentachlorocobaltate(III)
   This compound consists of a cobalt ion (Co3+) in the +3 oxidation state, coordinated with five chloride ions (Cl−) and one water molecule (H2O), with potassium (K+) acting as a counterion.
   The formula would be:
   K[CoCl5(H2O)]Explanation:
   • “Aquapenta” means one water molecule (H2O) is coordinated with the cobalt ion.
   • “Chlorocobaltate” indicates five chloride ions (Cl−) bound to the cobalt ion.
   • The cobalt ion is in the +3 oxidation state (Co3+), as denoted by “(III)”.
   • Potassium (K+) is the counterion that balances the overall charge of the complex.

In summary, the chemical formulas are:

1. Mn(CO)2Cl2Br
2. [Pt(NH3)4Br2]Br
3. K[CoCl5(H2O)]
