Answer:

The correct option is (A) Colourless.

Explanation :

  • When there will be a difference in the crystal field splitting energy in compounds, then it gives co-ordination compounds their hues. This phenomenon is also known as d-d transition. The term "d-d transition" refers to the movement of an electron or electrons from a lower energy d orbital to a higher energy d orbital by energy absorption, and vice versa. The complementary hues are produced when the electrons in the ground state absorb visible light and move to a higher energy level.
  • Due to splitting of energy levels, if causes a different energy gap between the energy levels of eg and t2g in them.
  • As a result, distinct frequencies corresponding to different energy gaps are radiated when electrons undergo transition.
  • It is an unpaired electron that typically oscillates between the different orbitals that are available.
  • Unpaired electrons assist create more energy levels in magnetic and electric fields (the Zeeman and stark effect), adding more lines to the spectrum. All of these demonstrate the distinctiveness of the radiated spectral distribution and, consequently, the colour.
  • So, since Hydrated Duo doesn't have an unpaired electrons, no d-d transition will take place and hence, the compound will be colourless.
