Vedclass · Answer

(C) $1$. The complex is $[Co(en)_3]^{3+}$, where $Co^{3+}$ is the central metal ion.$2$. The ligand $en$ stands for ethylenediamine $(NH_2CH_2CH_2NH_2)$, which is a bidentate ligand.$3$. $A$ bidentate ligand donates two lone pairs of electrons to the central metal ion.$4$. The coordination number is calculated as: $	ext{Number of ligands} 	imes 	ext{denticity} = 3 	imes 2 = 6$.$5$. Therefore, the coordination number of the central metal ion is $6$.

What is the coordination number of the central metal ion in the $[Co(en)_3]^{3+}$ complex?
