why is it that rate of haloform rxn is same with respect to all the halogens when r.d.s of rxn is loss of leaving group. good LGS are usually weak bases that is rate of rxn when CI3- is l.g should be faster than that with CF3- . That is it should indeed depend upon the halogen used along with OH- AS REACTANT

In the acid-catalyzed halogenation of aldehydes and ketones, the reaction rate is independent of the concentration of the halogen; chlorination, bromination, and iodination all occur at the same rate. Formation of the enolate is rate-determining, and, once formed, the enolate ion reacts rapidly with the halogen.
