Question

Among the following complexes of Cu^+2: cuCl_4^-2, Cu(CN)_4^-2, Cu(NH_3)_4^+2, the one that absorbs the shortest wavelength is: _____ the name of the compound with the formula: [Co(NH_3)_3 (H_2 O)(CO)Br]SO_4 is: Among the compounds: [Co(NH_3)_3 Cl]SO_4; K[Co(NH_3)]Cl_3; [Co(NH_3)]Cl_3, the one that shows stereoisomerism is: _____ A transition metal complex ion with octahedral geometry absorbs light of lambda_max 484 nm wavelength. The crystal field splitting, Delta, in kJ for this complex is: _____ kJ (h = 6.626 times 10^-34 J.s and C = 3.0 times 10^8 m/s and 1m = 1 times 10 nm). you can show your calculations here.

Explanation / Answer

7) Among the given complexex the one which has strong field ligand will split more ,hence more energy gap and we will require short wavelength of light.the complex is Cu(CN)42-

8)

triammineaquabromocarbonylcobalt(iii) sulphate
