Vedclass · Answer

(B) $EDTA^{4-}$ is a hexadentate ligand that forms a complex with $Co^{3+}$ ion. In the $[Co(EDTA)]^{-}$ complex,the $Co^{3+}$ ion is octahedrally coordinated by two nitrogen atoms and four oxygen atoms from the $EDTA^{4-}$ ligand. To find the number of $N-Co-O$ bond angles,we look at the coordination geometry. Each nitrogen atom is bonded to the cobalt center and is part of three five-membered chelate rings. Specifically,each $N$ atom is involved in $N-Co-O$ angles with the oxygen atoms of the acetate groups. By analyzing the structure,each of the two $N$ atoms forms $4$ such $N-Co-O$ angles (where the $O$ atom is one of the four coordinated oxygen atoms). Therefore,the total number of $N-Co-O$ bond angles is $2 	imes 4 = 8$.
