Question

If $Cd{I_2}$ is pink in colour, the $CdC{l_2}$ will be ‘_________’ colored.
A.Yellow
B.Red
C.Blue
D.Cannot be predicted.

Answer 1

Hint: A chemical compound is a substance made up of numerous identical molecules bound together by chemical bonds and made up of atoms from different elements. As a result, a molecule made up of only one element's atoms is not a compound.

Complete answer:
$Cd{I_2}$ - Cadmium iodide is a cadmium and iodine chemical combination. It has a crystal structure that is characteristic of substances with high polarization effects.
The iodide anions form a hexagonal densely packed arrangement in cadmium iodide, while the cadmium cations alternately cover all of the octahedral positions. The layered lattice that results is the final structure.
Many additional salts and minerals have the same basic structure. Cadmium iodide is primarily ionically linked, but it also has certain covalent properties.
$CdC{l_2}$ - Cadmium chloride is a white crystalline cadmium-chlorine combination. This salt is a hygroscopic solid with a high-water solubility and a low solubility in alcohol. It has a significant covalent aspect to its bonding, while being termed ionic.
 The crystal structure of cadmium chloride (explained below) is a model for defining other crystal structures since it is made up of two-dimensional layers of ions.
In $Cd{I_2}$ pink color is due to polarization of iodine by cadmium ions having a pseudo noble gas configuration.
Whereas in $CdC{l_2}$ extent of polarization of chloride ion by cadmium ion is less reactively so specific color can’t be predicted.
So, the final answer is option (D) i.e., Cannot be predicted.

Note:
The color of light is determined by the quantity of valence electrons present in a compound's outermost orbit. These electrons absorb a specific wavelength of visible light and emit a color that is complementary to the wavelength absorbed.
