EDTA has coordination numberA. 3B. 4C. 5D. 6

1.	EDTA has coordination numberA. 3B. 4C. 5D. 6
Answer» Correct Answer - D Coordination number of the central atom or ion is determined by the number of sigma bonds formed by the ligand with the central atom or ion . `therefore ` EDTA (Ethylene diaminetetraacetate ) has `CN =6` `{:(""^(-)OOCH_(2)C" "CH_(2)COO^(-)),(" "" /"),( " "overset(..)N- CH_(2) -overset(..)N),(" /"" "),(""^(-)OOCH_(2)C" "CH_(2)COO^(-)),(" EDTA"):}`
