In which of the following solvents, should KBr be soluble at 25∘C (D is the dielectric constant)?

The correct option is C CH3OH(D=32)Like dissolves like. Since KBr is a polar ionic compound, it will be soluble in a polar solvent. The solvent with a higher value of dielectric constant will provide maximum solubility. It will be most soluble in polar solvents, i.e. with the highest value of D.

In which of the following solvents, should $K B r$ be soluble at $25^{\circ} C$ ( $D$ is the dielectric constant)?
