Answer 2

d electronic configuration of [Ru(en)₃]Cl₂ and [Fe(H₂O)₆]Cl₂

Explanation:

• In complex [Ru(en)₃]Cl₂, metal Ru is in +2 state. Metal Ru belongs to 4d-series thus en group behave as strong field group. Therefore, en group will behave as low spin group which means pairing of electrons in d orbital will take place.
• So, electronic configuration of Ru⁺² is [Kr] 4d⁶.
• Therefore, d electronic configuration of Ru⁺² in complex [Ru(en)₃]Cl₂ is t₂g⁶ eg⁰.
• In complex [Fe(H₂O)₆]Cl₂, metal Fe is in +2 state. Metal Fe belongs to 3d-series thus H₂O group behave as weak field group. Therefore, H₂O group will behave as high spin group which means pairing of electron is absent in d orbital.
• So, electronic configuration of Fe⁺² is [Ar] 3d⁶.
• Therefore, d electronic configuration of Fe⁺² in complex [Fe(H₂O)₆]Cl₂ is t₂g³ eg².
