Question

Quizplus · Accepted Answer

The formula for pentaamminechlorocobalt(III) chloride is [Co(NH3)5Cl]Cl. Here, NH3 is the ligand and Cl is the anion. In the formula for this compound, NH3 is present five times and Cl is present twice. Therefore, the correct formula is [Co(NH3)5Cl]Cl2. However, the given options have different subscripts for Cl, which indicates the number of chlorine atoms in the compound. Only option B has the correct subscript for Cl, which is 1 as there is only one Cl in the ligand sphere. Therefore, option B is the correct choice.
