$F_2 > Cl_2 > Br_2 > I_2$ $(	ext{Oxidising power})$

Vedclass · Answer

(C) Halogens have a strong tendency to accept electrons,making them strong oxidizing agents.The oxidizing power of halogens decreases down the group from fluorine to iodine due to the decrease in standard reduction potential.The correct order of oxidizing power is $F_2 > Cl_2 > Br_2 > I_2$.Option $A$ is incorrect because the electron affinity of $Cl$ is greater than $F$ due to inter-electronic repulsion in the small $2p$ orbital of $F$.Option $B$ is incorrect because $F_2$ has the lowest bond dissociation energy among halogens due to high inter-electronic repulsion between lone pairs.Option $D$ is incorrect because the reducing power of halide ions increases down the group $(I^{-} > Br^{-} > Cl^{-} > F^{-})$.
