1.	In the following complexes(a) : [Co(NH3)6]3+, (b) : [Co(en)3]3+, (c) : [Co(H2O)6]3+Identify the correct order of absorption of energy.(1) c < a < b(2) a < b < c(3) c < b < a(4) a < c < b
Answer» Correct option is (1) c < a < b All are Co3+ complex so stronger the ligand, greater is splitting of d orbital and greater is amount of energy absorbed. Order of strength of ligands: en > NH₃ > H₂O \(E = \frac{hc}\lambda\)

Answer»

Correct option is (1) c < a < b

All are Co3+ complex so stronger the ligand, greater is splitting of d orbital and greater is amount of energy absorbed.

Order of strength of ligands: en > NH₃ > H₂O

\(E = \frac{hc}\lambda\)
