The correct Answer is:
To determine the nature of the compound formed during the estimation of nickel, specifically nickel dimethylglyoxime, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Compound**: The compound in question is nickel dimethylglyoxime, which is formed when nickel ions react with dimethylglyoxime (DMG). 2. **Understand the Reaction**: Nickel (Ni²⁺) ions react with dimethylglyoxime, which has two nitrogen atoms that can coordinate with the nickel ion. The reaction can be represented as: \[ \text{Ni}^{2+} + 2 \text{DMG} \rightarrow \text{Ni(DMG)}_2 \] where DMG acts as a bidentate ligand. 3. **Formation of the Complex**: In the complex, the nickel ion is surrounded by two dimethylglyoxime molecules, forming a chelate complex. The bonding involves coordination between the nitrogen atoms of DMG and the nickel ion. 4. **Characterize the Complex**: The resulting nickel dimethylglyoxime complex is a scarlet red solid, indicating that it has distinct properties. 5. **Determine the Type of Bonding**: The bonding in this complex is primarily coordinate covalent bonding, where the nitrogen atoms donate lone pairs to the nickel ion. However, since the complex does not exhibit ionic characteristics (no transfer of electrons), it is classified as a non-ionic complex. 6. **Conclusion**: Thus, the compound nickel dimethylglyoxime is classified as a non-ionic complex. ### Final Answer: The compound is a **non-ionic complex**. ---
