6a.
the answer is [Cr(H2O)6]3+
Explanation: crystal field splitting is directly proportional to ligand field strength. when the ligand strength increases, crystal field splitting also increases. in the above case H2O is stronger ligand compare to chloro ligand, therefore, complex [Cr(H2O)6]3+ will have larger crystal field splitting.
6b.
The answer is [Cr(H2O)6]3+
Explanation: wavelength is inversely proportional to the energy. when complex has large crystal field splitting energy then it will have a shorter wavelength. since [Cr(H2O)6]3+ have large crystal field splitting energy then it will have shorter wavelengh.

Crystal Field Question.
I understand that octahedral shapes have larger splitting energies
then in tetrahedral complexes. And it would take more energy to
split more electrons. So would the order be from Highest to Lowest:
B>A>C where A, B, C are the compounds listed in their
respective orders.
