Vedclass · Answer

(D) The ionic character of the metal-halogen bond depends on the electronegativity difference between the metal and the halogen. As we move down the group from $F$ to $I$,the electronegativity of the halogen decreases,leading to a decrease in the ionic character of the $M - X$ bond. Additionally,according to Fajan's rule,as the size of the halide ion increases,the covalent character increases,which implies that the ionic character decreases in the order $M - F > M - Cl > M - Br > M - I$.

In which of the following orders does the ionic character of the metal-halogen $(M - X)$ bond decrease?
