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.
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.
The addition of one equivalent of hydrogen chloride or hydrogen bromide converts alkynes to haloalkenes. The addition of two or more equivalents of HCl or HBr converts alkynes to geminal dihalides through an haloalkene intermediate. These additions are regioselective and follow Markovnikov's rule.

1-Hexyne is a hydrocarbon consisting of a straight six-carbon chain having a terminal alkyne. Its molecular formula is HC 2 C 4 H 9. A colorless liquid, it is one of three isomers of hexyne. [1] It is used as a reagent in organic synthesis.
Take the reaction of alkynes with HX, for instance. The reaction often can be stopped with the addition of 1 equivalent of HX, but reaction with an excess of HX leads to a dihalide product. For example, reaction of 1-hexyne with 2 equivalents of HBr yields 2,2-dibromohexane.
Hydration is the process where water is added to an alkene to yield an alcohol. Acid-catalyzed hydration is when a strong acid is used as a catalyst to begin the reaction, but let's look at the mechanism below and break down the steps. Step 1: A hydrogen atom from the acid is attacked by the nucleophilic Pi-electrons in the double bond.
