Furfuryl chloride can undergo substitution by both S_N2 and S_N1 mechanisms. Since it is a 1° alkyl halide, we expect S_N2 but not S_N1 reactions. Draw a mechanism for the S_N1 reaction shown below, with careful attention to the structure of the intermediate. How can this primary halide undergo S_N1 reactions? Why is there no competition with E2 or E1 mechanisms?
