Which of the following matches between a property and the corresponding chemical species are correct — Chemical Bonding Chemistry Question

💡 Solution & Explanation

A: $I^-$ is the largest, hence most polarizable. B: $Al^{3+}$ has the highest charge-to-size ratio. C: $F^-$ is the least polarizable, minimizing covalent character and maximizing ionic character. D is incorrect; $AgF$ is more ionic and thus more soluble in polar water, whereas $AgI$ is highly covalent and insoluble.
