The SN2 reaction is responsible for taking 1-butanol and converting it to 1-bromobutane. SN2 and SN1 are reactions that take acids and catalyze them to create alkyl halides.
Tertiary alcohols follow the SN1 reaction path and primary alcohols follow the SN2 reaction path. The SN2 reaction that converts 1-butanol to 1-bromobutane is a rapid protonation of the alcohol and involves a nucleophile attacking the carbon, which leads to the displacement of the water. This nucleophile attack is best for primary substrates, which is why it is used by primary alcohols and 1-butanol.
SN2 is also a nucleophilic substitution. In a nucleophilic substitution, the reaction is of an electron pair donor with an electron pair receptor.
1-butanol is known as butyl bromide. It is a colorless or pale, straw-colored liquid that is highly flammable. It is best for only experienced individuals to handle 1-butanol in a lab setting because its highly flammability is possible cause for concern. 1-butanol is known to have the molecular formula of C4H10O and a molecular weight of 74.1216. It is a four carbon linear hydrocarbon with a hydroxy group at the first position. It is used in human medication as a bactericide that treats "frothy bloat." It is also used to help patients in postoperative pain in otolaryngeal surgery or those who are in a far advanced stage of cancer.
