What is the formula of Dichloro-Bis-ethylenediamine cobalt (II)?
Correct answer: A. [Co(en)2Cl2]
- A. [Co(en)2Cl2]
- B. [Co(en)2Cl2]2-
- C. [Co(ebn)2Cl2]1-
- D. [Co(en)2Cl2]1+
Explanation
The correct formula for Dichloro-Bis-ethylenediamine cobalt (II) is [Co(en)2Cl2]. This complex is neutral, with cobalt in the +2 oxidation state, two ethylenediamine ligands acting as bidentate ligands, and two chloride ions. The other options incorrectly suggest charges or use incorrect ligands (e.g., 'ebn' instead of 'en'). Option B and D suggest incorrect charges, while Option C uses an incorrect ligand abbreviation.
