Which of the following silver halides possesses the highest covalent character? — Chemical Bonding Chemistry Question

💡 Solution & Explanation

According to Fajan's rules, covalent character in an ionic bond increases with the size of the anion, as larger anions are more easily polarizable. Among the halides, the size increases in the order $F^- < Cl^- < Br^- < I^-$. Therefore, $AgI$ is the most polarizable and exhibits the highest covalent character.
