Question 1

The complex ion NiCl42– is tetrahedral. The number of unpaired electrons in the complex is:

◦ 0
◦ 1
◦ 2
◦ 3
◦ 4

Question 2

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

◦ Zn2+ is paramagnetic.
◦ Zn2+ exhibits “d orbital” splittings in its complexes such that they absorb all wavelengths in the visible region.
◦ Since Zn2+ is a d10 ion, it does not absorb visible light even though the “d orbital” splittings are correct for absorbing visible wavelengths.
◦ Zn2+ is not a transition metal ion.
◦ None of these are correct.
