Vedclass · Answer

(A) $MnO_2$ acts as an oxidizing agent in acidic medium. It can oxidize $Cl^-$,$Br^-$,and $I^-$ to their respective halogens ($Cl_2$,$Br_2$,$I_2$). However,$F^-$ has a very high standard oxidation potential and is the strongest reducing agent among halides,while $F_2$ is the strongest oxidizing agent. Therefore,$MnO_2$ cannot oxidize $F^-$ to $F_2$.
