Question

[Cr(NH₃)₆]³⁺ ion is ______.

विकल्प

• paramagnetic

• diamagnetic

• square planar

• tetrahedral

Answer 1

[Cr(NH₃)₆]³⁺ ion is paramagnetic.

Explanation:

The [Cr(NH₃)₆]³⁺ ion is a coordination complex where Cr³⁺ is the central metal ion coordinated to six NH₃ (ammonia) ligands. It has a +3 charge on the metal ion and exhibits an octahedral geometry due to the coordination number of 6. The complex is high-spin (due to the weak field ligand NH₃) and is paramagnetic because of the presence of unpaired electrons in the d-orbitals of Cr³⁺.
