Vedclass · Answer

(A) The basic strength of an anion is inversely proportional to the acidic strength of its conjugate acid.The conjugate acids of the given halides are $HF$,$HCl$,$HBr$,and $HI$.The acidic strength order of these hydrohalic acids is $HI > HBr > HCl > HF$.Since the acidic strength decreases from $HI$ to $HF$,the basic strength of the corresponding conjugate bases increases in the order $I^{-} Therefore,the order of decreasing basic strength is $F^{-} > Cl^{-} > Br^{-} > I^{-}$.Thus,the correct option is $A$.

The order of decreasing basic strength of halides is:
