Vedclass · Answer

(D) The coordination number is the total number of coordinate bonds formed between the central metal ion and the ligands attached to it.In the complex $[Co(en)_2Cl_2]$,the ligands are ethylenediamine $(en)$ and chloride ions $(Cl^-)$.Ethylenediamine $(en)$ is a bidentate ligand,meaning each $en$ molecule forms $2$ coordinate bonds. Thus,$2$ $en$ molecules form $2 	imes 2 = 4$ bonds.Chloride $(Cl^-)$ is a monodentate ligand,meaning each $Cl^-$ ion forms $1$ coordinate bond. Thus,$2$ $Cl^-$ ions form $2 	imes 1 = 2$ bonds.The total coordination number is $4 + 2 = 6$.
