In which of the following solvents, KI has highest solubility? — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Recall that the solubility of ionic compounds (like KI) in a solvent is directly proportional to the dielectric constant (ε) of the solvent. Step 2: A higher dielectric constant weakens the electrostatic forces holding the ionic lattice together, allowing the ions to solvate and dissolve more easily. Step 3: Among the given solvents, CH3OH has the highest dielectric constant (ε = 32). Therefore, KI has the highest solubility in CH3OH, matching option (c).
