What alkene could you use to make the following products? Draw the structure of the alkene, and tell what other reagent is also required for the reaction to occur.

d. Chemical structure of a cyclopentanol molecule with a hydroxyl group (OH) attached.

Accepted Answer

All right. Hi, everyone. So this question has two parts to it. Part one says to draw the structure of the alkane reactant that was used to make the following product. And part two says to identify the other reagent required for the reaction to occur. So our product is cyclohexane and cyclohexane is an alcohol, right? So the reaction that's required in this case, given the fact that our reactant has to be an all keen is going to be the acid catalyzed hydration. O OK. Recall that if you have an a keen here, any generic or keen, then an alkene is going to react with water in the presence of a sulfuric acid catalyst. So what happens here is a hydration or the addition of water across both carbons in your double bond. And what I mean by that is that one carbon receives hydrogen and the other carbon receives an oh group thereby giving water across both carbons. Now, the example that I illustrated in this case involves an unsymmetrical alkene, which meant that the hydroxy group goes on the more substituted carbon. But if we consider the structure of cyclo Heino, right, all carbons inside of the ring are essentially equal, right? Because there's an element of symmetry to this molecule. So if we consider the position of the hydroxy group on carbon one of the cyclohexane ring, then carbons two and three will produce the same product, right, a double bond between carbons, one and two, or between carbons, one and three would yield the same product. So maybe it would, it would have been better to number it all across, right? So either carbons one or 21 in two or one in six. So when we consider the identity of the keen reacted, we would simply add a double bond in between carbon one and either of the two carbons adjacent to it on the rink because either way we would get the same product due to there being a element of symmetry to this molecule. So heres the answer for part one and now for part two, as discussed previously, this is an acid catalyzed hydration, which means that the other reactants are going to be H2O and H two. So four and there you have it. Here is your final answer for both parts. So with that being said, thank you so very much for watching. And I hope you found this helpful.
