Current Question (ID: 18700)

Question:
$\text{The correct statements about ethane-1,2-diamine as a ligand are:}$ $\begin{array}{ll} (a) & \text{It is a neutral ligand} \\ (b) & \text{It is a bidentate ligand} \\ (c) & \text{It is a chelating ligand} \\ (d) & \text{It is a unidentate ligand} \end{array}$
Options:
  • 1. $\text{a, b and b}$
  • 2. $\text{b and c}$
  • 3. $\text{a, b and c}$
  • 4. $\text{a, c and d}$
Solution:
$\text{HINT- Molecular formula of ethane-1,2-diamine is } \text{C}_2\text{H}_4(\text{NH}_2)_2$ $\text{STEP 1: (a) Ethane-1,2-diamine is a neutral ligand due to absence of any charge.}$ $\text{(b) It is a bidentate ligand due to presence of two donor sites one at each nitrogen atom of amino group.}$ $\text{(c) It is a chelating ligand due to its ability to chelate with the metal.}$ $\text{STEP 2: The structure of ethane-1,2-diamine is:}$ $\text{(Image of structure)}$ $\text{Hence, options (a), (b) and (c) are correct choices.}$
