Hi. Apparently with chlorobutane to sodium iodide
1-chlorobutane with NaI <-- SN2
2-chlorobutane with NaI <--SN1 & SN2
for sodium metal to chlorobutane, always keep in mind the concept of spectator atom where; you have a metal spectator atom, realize that the non-metal next to it must have negative charge.
OR"

so, by this elimination reaction of alkyl halide with nucleophile(sodium metal in this case), resultant can be easily depicted.
