JEE Main Chemistry question

In the case of alkali metal halides, the covalent character decreases in the order

(A)MI > MBr > MCl > MFCorrect
(B)MCl > MI > MBr > MF
(C)MF > MCl > MBr > MI
(D)MF > MCl > MI > MBr

Answer: (A)

Solution

For a fixed alkali metal cation, covalent character of the halide increases with increasing size (polarisability) of the halide anion: is the largest and most
