Problem

In a series of experiments between various halogen solutions with aqueous halides, the following results were obtained.

	Halide $X^{-}(aq)$	Halide $Y^{-}(aq)$	Halide $Z^{-}(aq)$
Halogen $X_{2}(aq)$	no reaction	reaction	no reaction
Halogen $Y_{2}(aq)$	no reaction	no reaction	no reaction
Halogen $Z_{2}(aq)$	reaction	reaction	no reaction

Which is the correct likely identity of X, Y and Z? a. X = fluorine, Y = chlorine, Z = iodine b. X = bromine, Y = iodine, Z = chlorine c. X = iodine, Y = bromine, Z = chlorine d. X = fluorine, Y = iodine, Z = bromine
