Why must the crude alkyl halide product be dried carefully ...

Because any water contaminating the alkyl halide, will likely also contaminate the distillate. Water often azeotropes with organic compounds, sometimes at much lower temperatures than 100 ""^@C. Thus, it makes sense to dry the alkyl halide before distillation, especially if the halide is going to be used for say a Grignard or lithium reagent reaction.
