How do we order the folllwing considering how easily they grab H^+ ions, when dissolved in liquid ethanoic acid?

Question

1)OH^-
2)F^-
3)Cl^-
4)Br^-
5)I^-

I think the correct order is 5<4<3<2<1,because I^- is strong acid cation and may not like to grab H^+ ions etc.Am I correct?

Answer 1

I can't help with this as my knowledge of using acetic acid as a solvent is limited.

Answer 2

Never mind and thank you!
