Q33. Match List I and with List II (List I: Complex ions A. [CoCl(NH3)5]2+, B. [Co(NH3)5(H2O)]3+, C.

Q: What is the correct answer for CUET UG Chemistry Q33?

The correct answer is c. The wavelength of light absorbed by a coordination complex is inversely proportional to the ligand field strength. Stronger ligands cause greater splitting (higher energy, shorter wavelength). Based on the spectrochemical series (CN⁻ > NH3 > H2O > Cl⁻): D. [Co(CN)6]³⁻ has the strongest ligand, absorbing the shortest wavelength (IV: 310 nm). C. [Co(NH3)6]³⁺ is next in strength (III: 475 nm). B. [Co

FirstInTest · Accepted Answer

The wavelength of light absorbed by a coordination complex is inversely proportional to the ligand field strength. Stronger ligands cause greater splitting (higher energy, shorter wavelength). Based on the spectrochemical series (CN⁻ > NH3 > H2O > Cl⁻): D. [Co(CN)6]³⁻ has the strongest ligand, absorbing the shortest wavelength (IV: 310 nm). C. [Co(NH3)6]³⁺ is next in strength (III: 475 nm). B. [Co(NH3)5(H2O)]³⁺ is weaker due to H2O (I: 500 nm). A. [CoCl(NH3)5]²⁺ is weakest due to Cl⁻ (II: 535 nm). Therefore, the correct match is A-II, B-I, C-III, D-IV.
