... system allowing the mixture to be heated to an elevated temperature for an extended period of time without the loss of material. Since n-Butyl bromide is immiscible in water, the method of extraction by differing solubilities was used to separate the water miscible components. The starting materials were weighed, and the product was weighed to calculate the yield. The amount of ... experiment will primarily be centered on nucleophilic aliphatic substitution reactions, which can be further classified between SN1 and SN2 reactions. A technique called extraction was also used in this exper...
