The purpose of this experiment is to execute an alkene hydration reaction with 1-hexene. We want to do this with an acid catalyst and end up with an alcohol. From this we want to determine whether the major alcohol product was 1-hexanol or 2-hexanol.

16 gru 2021 · The mechanism for acid-catalyzed hydration of alkene is essentially the same as the mechanism for the addition of hydrogen halide, HX, to alkenes, and the reaction therefore follows Markovnikov’s rule as well in terms of regioselectivity. The hydration of 1-methylcyclohexene and the reaction mechanism are shown below.
23 kwi 2016 · 1) This reaction is an acid-catalyzed hydration as follows: What we have going on is that: The strong-acid solution, presented as #"H"^(+)# for shorthand, contains protonated water (i.e. #"H"_3"O"^(+)#). The hydronium protonates the alkene to generate a carbocation intermediate.

Not all acid-catalyzed conversions of alcohols to alkyl halides proceed through the formation of carbocations. Primary alcohols and methanol react to form alkyl halides under acidic conditions by an S N 2 mechanism. In these reactions the function of the acid is to produce a protonated alcohol.
Tertiary alcohols react with either HCl or HBr at 0 °C by an S N 1 mechanism through a carbocation intermediate. Primary and secondary alcohols are much more resistant to acid, however, and are best converted into halides by treatment with either SOCl 2 or PBr 3 through an S N 2 mechanism.
