Synthesis of 1-Bromobutane
Synthesis of 1-bromobutane from 1-Butanol using the SN2 Reaction
Abstract:
The objective of this experiment is designed to study the synthesis of 1-bromobutane from 1 butanol using a SN2 reaction.. The product will then be analyzed using a flamed loop test by use of fire.
Reaction Mechanism: CH3CH2CH2CH2—OH H+ CH3CH2CH2CH2— +OH2 Br- CH3CH2CH2CH2—Br + H2O 1-butanol 1-bromobutane
Reagent Table: Reagent | MW (g/mol) | Den.(g/ml) | Bp (°C) | Mass/Vol | Mmoles | Equiv | 1-butanol | | | | | | | NaBr | | | | | | | Sulfuric Acid | | | | | | | Compound/Product | | | | | | | 1- bromobutane | | | | | | | | | | | | | |
Discussion:
SN2 reactions are substitution reactions that involve the exchanging of a group(s) in a molecule. Nucleophiles are electron donors and want to give them away to electron acceptors. If the leaving group is a bad leaving group.
In this experiment, I had foam in my flask from the microscale kit that could of caused an error in my desired product. The test tube 3 had sulfuric acid in it would not separate the layers. Due to this problem I had to swish the contents slowly using a pipette. The swishing process didn’t help to separate any layers, just made the product look turbid. Due to this I added a couple drops of water that helped the product to separate its layers.
Conclusion:
SN2 reactions are substitution reactions that are performed in organic labs. In this experiment 1-butanol was converted into 1-bromobutane by an SN2 reaction. The ending result of the experiment was to test if the product was correct by using a flame test that colorizes the product. The flame test turned green which in this case was an overall
