Answer #1

5. The preparation of n-butyl chloride from n-butanol using hydrobromic acid produce from the reaction of NaBr and H2SO4 is mainly undergoes SN2 reaction. This is because 1 deg alkyl halide due to less steric crowding prefers SN2 reaction. SN1 is not preferred as the 1 deg carbocation is not sufficient enough to undergo SN1 reaction.

    complete #1 and #2 and please explain! Nucleophilic Substitutions: Competing Nucleophiles Dry Lab Name When an alcohol (substrate) is placed in an excess equimolar amounts of chloride ions and bromide ions in acid media the corresponding alkyl halides are obtained. The ratio of the alkyl halides depends on several factors: the nature of the substrate, the reaction conditions, the solvent and the mechanism of the reaction.
