Correct answer
Co of [Cr(H2O)6]2+

< [Mo(H2O)6]2+ and

o of [Ti(H2O)6]3+ > [Ti(H2O)6]2+

Step-by-step explanation

0 of complex [Mo(H2O)6]2+ is greater than that of [Cr(H2O)6]2+. It is due to the fact that Mo2+ belongs to second row transition element while Cr2+ is first row transition element.

Magnitude of crystal field splitting energy (0) depends on the charge on the metal ion. Greater the charge, greater is the crystal field splitting energy. Therefore, [Ti(H2O)6]3+ > [Ti(H2O)6]2+.
