Vedclass · Answer

(B) According to Molecular Orbital Theory $(M.O.T.)$,the bond order is inversely proportional to the bond length.For $F_2^+$: Total electrons = $17$,Bond Order = $(10-7)/2 = 1.5$.For $F_2$: Total electrons = $18$,Bond Order = $(10-8)/2 = 1.0$.For $F_2^-$: Total electrons = $19$,Bond Order = $(10-9)/2 = 0.5$.Since the bond order follows the order $F_2^+ > F_2 > F_2^-$,the bond length follows the order $F_2^+ < F_2 < F_2^-$.
