The Complex Ions of Zn²⁺ Are All Colorless

question 83

Multiple Choice

The complex ions of Zn²⁺ are all colorless. The most likely explanation for this is that

• A) Zn²⁺ exhibits "d orbital" splittings in its complexes such that they absorb all wavelengths in the visible region.
• B) because Zn²⁺ is a d¹⁰ ion, it does not absorb visible light even though the "d orbital" splittings are correct for absorbing visible wavelengths.
• C) Zn²⁺ is paramagnetic.
• D) Zn²⁺ is not a transition metal ion.
• E) None of these explanations could be correct.
