Question

In which of the following solvent, KI has highest solubility:- (E = dielectric constant )

• A. $C_6{H}_6(E=0)$
• B. $\left(C{H}_3{)}_{2}CO\right(E=2)$
• C. $C{H}_{3}OH(E=32)$
• D. $CC{I}_4(E=0)$

Answer 1

The correct option is C $C{H}_{3}OH(E=32)$

KI is ionic in nature so, as dielectric constant increases solubility increases.
