Based on CFT, the correct relation between ∆o and ∆t is

Crystal field splitting in octahedral complexes is more than in tetrahedral complexes becauseI) Six ligands in octahedral complexes but only four ligands in tetrahedral complexes;II) Ligands approach along the axes in octahedral complexes whereas in between the axes in tetrahedral complexes;∆0=49 ∆t ;
