प्रश्न
A chelating agent has two or more than two donor atoms to bind to a single metal ion. Which of the following is not a chelating agent?
पर्याय
Thiosulphate
Oxalato
Glycinato
Ethane-1, 2-diamine

उत्तर
Thiosulphate
Explanation:
Geometry of thiosulphato is not favourable to chelate a metal ion. The lengand 'thiosulphato' is \[\ce{S2O3^-}\], has only one donor site, hence its geometry is not favourable to chelate a metal ion (i.e. for chetation)
