3+ is
◦ 0
◦ 1
◦ 2
◦ 3
◦ 4
Question 2
Two complex ions containing Ni are [Ni(NH
3)
6]
2+, which is blue, and [Ni(en)
3]
2+, which is purple. Which one of these statements is true?
◦ The crystal field splitting energy (Δ) is greater for [Ni(NH
3)
6]
2+ than for [Ni(en)
3]
2+.
◦ [Ni(en)
3]
2+ absorbs light in the violet region of the spectrum.
◦ Both complex ions are diamagnetic.
◦ The energy of the photon absorbed by [Ni(en)
3]
2+ is greater than that absorbed by [Ni(NH
3)
6]
2+.
◦ The wavelength of the light absorbed by [Ni(en)
3]
2+ is greater than the wavelength absorbed by [Ni(NH
3)
6]
2+.
