still had no reaction, so it was totally unreactive. Due to the carbocation intermediate step in the Sn1 reaction, the alkyl halides that could best stabilize the positive charge most quickly. 3 T-butyl chloride has stable tertiary carbocation and the allyl chloride has a carbocation that is stabilized by resonance, so they reacted first. N-butyl chloride and n-butyl bromide reacted at different rates because they are different leaving groups. The better or strong leaving group should react first. Chlorobenzene is not a reactive alkyl halide in a substitution reaction because the ring is incredibly stabilized. Part 2: In the second set of reaction tubes, we created conditions favorable to an Sn2 reaction. We used a small amount of a strong nucleophile, I-, in a polar aprotic solvent, acetone. After substitution with I-, and leaving the alkane, each halide precipitated out as a sodium salt. For our reaction tubes the n-butyl chloride got very cloudy white, then slowly faded away, but got cloudy after heating. The sec-butyl got cloudy but not as much as the n-butyl chloride and faded away quicker that the n-butyl chloride. After heat no precipitate reformed and therefor was unreactive.
