Answer» In facial isomer THREE same ligands occupy ADJACENT positions on OCTAHEDRON FACE In meridional isomers same ligands are present at `90^(@)" and "180^(@)` angles In facial isomer same ligands are present only at `90^(@)` angle Both isomers (facial and meridonial) are OPTICALLY active Answer :D
