Disclosed is a process involving contacting a hydrohalobutane selected from the group consisting of CF2HCHClCH2CCl2H, CF3CHClCH2CCl2H, CF3CHClCH2CCl3, CF3CClHCHFCCl2H and CF3CClHCHFCCl3, with HF in a reaction zone in the presence of an antimony halide catalyst selected from SbCl5 and SbF5 to form a first product mixture containing a hydromonochlorofluorobutane. Also disclosed is a process involving contacting a hydrohalopentane selected from the group consisting of CF2HCHClCH2CX2CX3 and CF3CHClCH2CX2CX3, wherein each X is independently selected from the group consisting of F and Cl, and not all X are fluorines, with HF in a reaction zone in the presence of an antimony halide catalyst selected from SbCl5 and SbF5 to form a first product mixture containing a hydromonochlorofluoropentane. A compound of the formula CF3CHClCH2CHF2 is also disclosed.
