The Total solution for NCERT class 6-12
Discuss briefly giving an example in eachcase the role of coordination compounds in:
(i) biological system
(ii) medicinal chemistry
(iii) analytical chemistry
(i) Role of coordination compounds in biologicalsystems:
We know that photosynthesis is made possibleby the presence of the chlorophyll pigment. This pigment is a coordinationcompound of magnesium. In the human biological system, several coordinationcompounds play important roles. For example, the oxygen-carrier of blood, i.e.,haemoglobin, is a coordination compound of iron.
(ii) Role of coordination compounds in medicinalchemistry:
Certaincoordination compounds of platinum (for example, cis-platin) areused for inhibiting the growth of tumours.
(iii) Role of coordination compounds in analyticalchemistry:
During salt analysis, a number of basicradicals are detected with the help of the colour changes they exhibit withdifferent reagents. These colour changes are a result of the coordinationcompounds or complexes that the basic radicals form with different ligands.
(iii) Role of coordination compounds in extractionor metallurgy of metals:
