Which of the following can be termed as mixed complex?a)[Co(NH3)4NO2Cl...
Explanation:
A mixed complex is a coordination compound that contains more than one type of ligand. In this case, the ligands are ammonia (NH3), nitrite (NO2), and chloride (Cl-).
a) [Co(NH3)4NO2Cl]Cl:
- The central metal ion is cobalt (Co).
- The ligands are ammonia (NH3), nitrite (NO2), and chloride (Cl-).
- The complex has a coordination number of 6, with four ammonia ligands, one nitrite ligand, and one chloride ligand.
- The complex is named tetraamminenitritochlorocobalt(III) chloride.
b) K4[Fe(CN)6]:
- The central metal ion is iron (Fe).
- The ligands are cyanide (CN-).
- The complex has a coordination number of 6, with six cyanide ligands.
- The complex is named potassium hexacyanoferrate(III).
c) K2FeSO4:
- The central metal ion is iron (Fe).
- The ligands are sulfate (SO4^2-).
- The complex has a coordination number of 6, with six sulfate ligands.
- The complex is named potassium ferrate(II) sulfate.
d) [Cu(NH4)]SO4:
- The central metal ion is copper (Cu).
- The ligands are ammonia (NH3) and ammonium (NH4+).
- The complex has a coordination number of 5, with one ammonia ligand and four ammonium ligands.
- The complex is named copper(II) ammonium sulfate.
Conclusion:
Out of the given options, only option 'a' [Co(NH3)4NO2Cl]Cl can be termed as a mixed complex because it contains more than one type of ligand (ammonia, nitrite, and chloride). The other options consist of complexes with a single type of ligand.
