The correct Answer is:
To analyze the assertion and reason provided in the question, we will break down the concepts involved step by step. ### Step 1: Understand the Assertion The assertion states that "EDTA is a hexadentate ligand." **Explanation**: EDTA (Ethylenediaminetetraacetic acid) is indeed a hexadentate ligand. This means it can form six bonds with a central metal ion. The term 'hexadentate' comes from 'hexa' meaning six and 'dentate' referring to the number of donor atoms that can attach to the metal. ### Step 2: Understand the Reason The reason given is "Denticity of a ligand is given by the number of lone pairs donated to the central atom by a ligand." **Explanation**: Denticity refers to the number of donor atoms in a ligand that can bond to a central metal atom. In the case of EDTA, it has four carboxylate groups (each donating one pair of electrons) and two amine groups (each donating one pair of electrons). Thus, it can donate a total of six pairs of electrons to the metal ion, confirming its classification as a hexadentate ligand. ### Step 3: Conclusion Both the assertion and the reason are true. The assertion that EDTA is a hexadentate ligand is correct, and the reason provided accurately describes how denticity is determined. ### Final Answer: - **Assertion**: True - **Reason**: True - **Conclusion**: Both the assertion and reason are correct. ---

    Assertion Glycinate ion is an example of monodentate ligand Reason It contains N as the only donor atom .

    The ions or molecules bound to the central atom/ion in the coordination entity are called ligands. These may be simple ions such as Cl^(-) , small molecules such as H_(2)O or NH_(3) , larger molecules such as H_(2)NCH_(2)CH_(2)NH_(2) or N(CH_(2)CH_(2)NH_(2))_(3) or even macromolecules, such as proteins. When a ligand is bound to a metal ion through a single donor atom, as with Cl^(-), H_(2)O or NH_(3) , the ligand is said to be unidentate. When a ligand can bind through two donor atoms as in H_(2)NCH_(2)CH_(2)NH_(2) (ethane-1, 2-diamine) or C_(2)O_(4)^(2-) (oxalate), the ligand is said to be didentate and when several donor atoms are present in single ligand as in N(CH_(2)CH_(2)NH_(2)_(3) , the ligand is said to be polydentate Ethylenediamineteraacetate ion [EDTA^(4-)] is an important hexadentate ligand. It can bind through two nitrogen and four oxygen atoms to a central metal ion. What is meant by the term ligand ?
