Question

Explain difference in color which arises due to cis and trans form of[CO(en) 2cl2] complex?​

Answer 1

so this Complex has two bidentate ligands therefore the cis form will be optically active and that transform will be optically inactive

so so since sis form is optically active it will allow the plane polarised light to rotate which will provide a colour to the compound while the transform will not allow plane polarized light to rotate it so show the colour appearing would be different ......

hope it will give you some idea
