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. Sn1 and sn2 in the lab i did some reactions in the lab and the results i got don’t make sense to me for some 1-bromobutane with nai sn2.

With the reactions carried out, the desired haloalkane products of 1-bromobutane and 2-chloro-2-methylbutane were obtained the s n 2 reaction allowed 1-butanol to be.
