Green

Vedclass · Answer

(D) The complex $[Ni(H_2O)_6]^{2+}$ contains $Ni^{2+}$ ion,which has a $d^8$ electronic configuration. In the presence of water ligands,which are weak field ligands,the $d-d$ transition occurs,resulting in the absorption of light in the red region. Consequently,the transmitted light appears green. Therefore,the aqueous solution of $[Ni(H_2O)_6]^{2+}$ is green in color.
