Question

3. Which of the following complex ions has the smallest d-orbital splitting energy (A)? (a) octahedral [OsClo] (b) tetrahedral [OsCl4] 4. Which of the following complex ions has the greatest d-orbital splitting energy (A)? (A) [Rh(OH2)] (B) [Rh(ox)] (C) [RhCl] (D) [Rh(NH)d (E) [Rh(CN)3 4. The longer the wavelength absorbed by a metal complex, the is Ao. (a) larger (b) smaller 5. An octahedral complex is high-spin, weak field when the value of A is smaller than the energy required to pair up the electrons. (TRUE or FALSE) 6. Which complex ion should absorb visible light of the longest wavelength lowest energy) (A) [Cr(HO)], or (B) [Cr(CN) 7. Which complex ion should absorb visible light of the shortest wavelength (highest energy), (A) [Mo(H20)J", or (B) [Mo(CN)J'

Explanation / Answer

3. (b) In general tetrahedral complexes have smaller splitting than octahedral complexes

4. (B) Bidentate ligands show more stability and hence more more splitting energy.

4. (b) smaller. Because wave length is inversely proportional to energy.

5. TRUE

6. (A) absorb at longest wave length as H2O is weak field ligand

6. (B) absorb at shortest wave length as CN- is strong field ligand.
