Can someone help me understand why it is not possible for 1-hexene and 2-
bromohexane to be separated by recrystallization, and the extraction techiniques. I know that distillation is the most effective technique. Is it because of the purity of the resulting compounds?

1-hexene and 2-bromohexane are both in liquid states. So they have similar solubility. However, the recrystallization technique can be used only when two different compounds have different solubility. 1-hexene and 2-bromohexane cannot be separated when using the recrystallization technique because this technique is used to dissolve mixture solid in a solvent at high temperature. The solution is then cooled until one of the compounds crystalizes.

Extraction technique also cannot be used to separate these two compounds because of the same property they have: they are nonpolar, resulting non acid-base extraction. Extraction technique is used to separate two different compounds to organic and aqueous layer, which means one phase of one solvent has to be polar and the other phase has to be nonpolar.
