The complex that can show optical activity is:

The electronic spectrum of [Ti(H?O)?]³? shows a single broad peak with a maximum at 20,300 cm?¹. The crystal field stabilization energy (CFSE) of the complex ion, in kJ mol?¹, is: (1 kJ mol?¹ = 83.7 cm?¹)

The one that is not expected to show isomerism is:

Simplified absorption spectra of three complexes ((i), (ii) and (iii)) of Mⁿ⁺ ion are provided below; their λ_max values are marked as A, B and C respectively. The correct match between the complexes and their λ_max values is:

(i) [M(NCS)₆]⁽⁻⁶⁺ⁿ⁾
(ii) [MF₆]⁽⁻⁶⁺ⁿ⁾
(iii) [M(NH₃)₆]ⁿ⁺
