Vedclass · Answer

(B) The coordination number of a central metal atom is the number of ligand donor atoms to which it is directly bonded.In the complex $[Co(en)_2Br_2]Cl_2$,the ligand $en$ (ethylenediamine) is a bidentate ligand,and $Br^-$ is a monodentate ligand.Coordination number $= (2 	imes 	ext{denticity of } en) + (2 	imes 	ext{denticity of } Br^-)$Coordination number $= (2 	imes 2) + (2 	imes 1) = 4 + 2 = 6$.

The coordination number of cobalt in the coordination compound $[Co(en)_2Br_2]Cl_2$ is ........ .
