Answer:
I₂ is more soluble in CCl₄ than water.
Explanation:
The idea of “like dissolves like” can better account as to why iodine (I₂) is a soluble substance in carbon tetrachloride (CCl₄) more than in water. The principle “likes dissolve likes”, holds that, polar solutes dissolve better in polar solvents and vise versa. Iodine is a nonpolar substance as there is little variation in the electronegativity of the atoms; therefore, charge density is unlikely. Likewise, carbon tetrachloride is a nonpolar solvent that are made of C-Cl bonds and because of the symmetry the molecule has tetrahedral, the polarities of the bonds cancel out each other. Water is a strongly polar solvent because the difference of electronegativity between hydrogen and oxygen atoms is relatively big which results in a big value of the dipole moment. This is the reason why iodine dissolves well in CCl4; both the solute and solvent are non-polar, and since the summation forces between both are of the same type, London dispersion forces, they easily mix.
Therefore, the correct answer choice is:
