Among the molecules, BiF3, BiCl3 BiBr3 and BiI3, the one which is most...
Explanation:
The color of a molecule is determined by its electronic transitions. When a molecule absorbs light, its electrons get excited to higher energy levels, and the energy difference between the ground and excited states determines the color of the molecule. The more the energy difference, the higher the frequency of light absorbed, and hence the more colored the molecule appears.
BiF3, BiCl3 and BiBr3 have their valence electrons in p orbitals, while BiI3 has its valence electrons in d orbitals. The energy difference between the p orbitals is smaller than that between the d orbitals. Hence, BiI3 has the largest energy difference and appears the most colored.
Therefore, the correct option is (D) BiI3.
